-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: esound Date: Wednesday, October 11th, 2000 19:00 MEST Affected SuSE versions: 6.3, 6.4, 7.0 Vulnerability Type: local user compromise Severity (1-10): 3 SuSE default package: yes Other affected systems: Linux systems using esound with unix domain socket support Content of this advisory: 1) security vulnerability resolved: esound problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information esound, a daemon program for the Gnome desktop, is used for sound replay by various programs such as windowmanagers and other applications. The esound daemon creates a directory /tmp/.esd to host a unix domain socket. Upon startup, the daemon changes the modes of the socket, but a race condition allows an attacker to place a symlink into the directory to point to an arbitrary file belonging to the victim. By consequence, an attacker may be able to change the permissions of any file belonging to the victim. If the victim's userid is root, the attacker may be able to change the modes of any file in the system. SuSE distributions before SuSE-6.3 were not vulnerable to this attack because unix domain sockets were not supported by the esound daemon as shipped with these distributions. The only efficient solution for the problem is to store the unix domain socket in a directory where only the user has write access to. The user's home directory is such a location. Update packages that fix the race conditions by placing the sockets into the user's home directory are available for download. It is recommended to apply the fix on systems where multiple users can access the local filesystem. Note: Not all filesystems support unix domain sockets. The fix might not work if the user's home directory is on such a filesystem (such as AFS, eg.). In such rare cases, administrators are usually aware of such limitations. SuSE default installations do not have this limitation. Download the update package from locations desribed below and install the package with the command `rpm -Fhv file.rpm'. The md5sum for each file is in the line below. You can verify the integrity of the rpm files using the command `rpm --checksig --nogpg file.rpm', independently from the md5 signatures below. i386 Intel Platform: SuSE-7.0 ftp://ftp.suse.com/pub/suse/i386/update/7.0/snd1/esound-0.2.19-15.i386.rpm 9d8addaa5ba29554a727eb34ae5189f4 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/esound-0.2.19-15.src.rpm a9724b99a96430b1b7c1f741a8e8d528 SuSE-6.4 ftp://ftp.suse.com/pub/suse/i386/update/6.4/snd1/esound-0.2.16-75.i386.rpm 6f32f0867d1597a5129d0516438d9cca source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/esound-0.2.16-75.src.rpm 94ca6842981f7a501300d9edfc5cbf73 SuSE-6.3 ftp://ftp.suse.com/pub/suse/i386/update/6.3/snd1/esound-0.2.15-21.i386.rpm 16a5804a2f27e62d73df40d206b047ca source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.3/zq1/esound-0.2.15-21.src.rpm c86689fd5d9f719135e1263dd5a38832 Sparc Platform: SuSE-7.0 ftp://ftp.suse.com/pub/suse/sparc/update/7.0/snd1/esound-0.2.19-15.sparc.rpm 112648ef64c351952f832b180fcca23c source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.0/zq1/esound-0.2.19-15.src.rpm a0bb3e3517ca83c13abd6827a8d2295e AXP Alpha Platform: SuSE-6.4 ftp://ftp.suse.com/pub/suse/axp/update/6.4/snd1/esound-0.2.16-75.alpha.rpm d2efefb21a6424a81e63788d972db49d source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.4/zq1/esound-0.2.16-75.src.rpm a69ebae320c6f118f4b9e07f2a9af4d2 SuSE-6.3 ftp://ftp.suse.com/pub/suse/axp/update/6.3/snd1/esound-0.2.15-21.alpha.rpm 19942e308eda0c0d505bb64da734ad8d source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.3/zq1/esound-0.2.15-21.src.rpm 6f337d6864111d27fa93ef2bc3cb7b5a PPC Power PC Platform: SuSE-7.0 ftp://ftp.suse.com/pub/suse/ppc/update/7.0/snd1/esound-0.2.19-16.ppc.rpm be6daabfee0e7e629b848814be81d9d0 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.0/zq1/esound-0.2.19-16.src.rpm c77475b2c8fff104f8662bb9179efb64 SuSE-6.4 ftp://ftp.suse.com/pub/suse/ppc/update/6.4/snd1/esound-0.2.16-75.ppc.rpm f0e1aa54c3fdf7c6c02b34bedc51ee0f source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/zq1/esound-0.2.16-75.src.rpm 9acd25b5521201386bb73bc707382646 ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - gnorpm A race condition has been found in the gnorpm program, a GUI for the rpm system. The issue will be addressed in a following announcement. - ncurses The ncurses library contains buffer overflows that are exploitable when user-supplied terminfo databases are processed. This imposes a security risk on programs/binaries that are linked against libncurses and run with special privileges. Both workaround and clean solution is to remove the suid bit from all executable files with setuid bit set. The issue will be addressed in a following security announcement. - apache mod_rewrite A bug has been discovered in the apache package that allows attackers to read arbitrary files on a system that runs apache. The responsible apache module named "mod_rewrite" is not used by default on SuSE installations of the apache package. The issue will be addressed in a following security announcement. - cfengine A format string parsing bug causes the cfengine package to be vulnerable to a remote root attack. Update packages are available, the security announcement is pending. - usermode/userhelper userhelper is a suid helper program designed to let the user who is logged on to the console execute some programs with root privileges. SuSE distributions do not contain the usermode package and therefore are not vulnerable to the security problems recently discovered in the usermode package. - tmpwatch The tmpwatch packages as shipped with SuSE distributions are not vulnerable to the attacks as discussed on security forums because we ship an older version that does not provide the functionality that can be exploited. - lprNG The versions of the lprNG package that come with SuSE distributions are not vulnerable to the format string parsing errors as discussed in security forums. - traceroute The traceroute program has been found vulnerable to a bug (`traceroute -g 1 -g 1') in many distributions. Newer SuSE distributions have a different implementation of the traceroute program and are not vulnerable to the bug found by Pekka Savola <pekkas(a)netcore.fi>. The vulnerability could not be verified in older SuSE distributions. ______________________________________________________________________________ 3) standard appendix: SuSE runs two security mailing lists to which any interested party may subscribe: suse-security(a)suse.com - general/linux/SuSE security discussion.

SuSE Security Announcement: syslogd/klogd

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: syslogd/klogd Date: Wednesday, September 20th, 2000 03:00 MEST Affected SuSE versions: 6.1 6.2, 6.3, 6.4, 7.0 Vulnerability Type: local DoS, possible root compromise Severity (1-10): 5 SuSE default package: yes Other affected systems: Linux systems, possibly unix systems Content of this advisory: 1) security vulnerability resolved: syslogd/klogd problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information The syslogd package consists of two daemons that are being launched upon system startup: klogd and syslogd. The former collects kernel messages and passes them on to the syslog(3) facility. syslogd will pick up the logging messages and write them to the logfiles as specified by the syslogd configuration file /etc/syslog.conf. Errors in both the klogd and the syslogd can cause both daemons do die when specially designed strings get passed to the kernel by the user, eg. with a malformed structure in a system call. These errors have been discovered by Jouko Pynnönen, Solar Designer, a fix for one of the bugs has been provided by Daniel Jacobowitz. There is currently no known way to exploit these bugs with an effect other than a DoS (Denial of Service) of the syslog/klog service. Since it may be possible to execute arbitrary code as a result of a buffer overflow, administrators should consider applying the patches as soon as possible. Also, logging messages resulting from firewall rules in the kernel can get lost if the daemon does not pick them up. Efficient temporary countermeasures against these attacks other than package upgrade do not exist. Download the update package from locations desribed below and install the package with the command `rpm -Fhv file.rpm'. The md5sum for each file is in the line below. You can verify the integrity of the rpm files using the command `rpm --checksig --nogpg file.rpm', independently from the md5 signatures below. i386 Intel Platform: SuSE-7.0 ftp://ftp.suse.com/pub/suse/i386/update/7.0/a1/syslogd-1.3.33-161.i386.rpm 284b1975cda65cd6ed5ce65672706e19 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/syslogd-1.3.33-161.src.rpm 49c7a171753171f4e6fd772453d46a93 SuSE-6.4 ftp://ftp.suse.com/pub/suse/i386/update/6.4/a1/syslogd-1.3.33-161.i386.rpm cb89ed419b0c9dbf7c66191a58606920 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/syslogd-1.3.33-161.src.rpm 33686198aa6412401b0056241829aae0 SuSE-6.3 ftp://ftp.suse.com/pub/suse/i386/update/6.3/a1/syslogd-1.3.33-161.i386.rpm af5e43976fb9814e1f5d626e16c2d176 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.3/zq1/syslogd-1.3.33-161.src.rpm 1e821f6fda1f471d36e9b4990aa496b4 SuSE-6.2 ftp://ftp.suse.com/pub/suse/i386/update/6.2/a1/syslogd-1.3.33-9.i386.rpm fc29df9455288f40eb1e8dbd0f47d5b3 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.2/zq1/syslogd-1.3.33-9.src.rpm ae980989a754e6bf85de9dd60676b321 SuSE-6.1 ftp://ftp.suse.com/pub/suse/i386/update/6.1/a1/syslogd-1.3.33-161.i386.rpm c8d23ec6c3a9f944c15d6e12ffebc66f source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.1/zq1/syslogd-1.3.33-161.src.rpm b0329c20caf1d1d427da9961240732f5 SuSE-5.3 ftp://ftp.suse.com/pub/suse/i386/update/5.3/a1/syslogd-1.3.33-9.i386.rpm 3104e26a8b474e215ed703b7c4d48888 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/5.3/zq1/syslogd-1.3.33-9.src.rpm 09c9539df1c4225d2366a2a860b01dbb Sparc Platform: SuSE-7.0 ftp://ftp.suse.com/pub/suse/sparc/update/7.0/a1/syslogd-1.3.33-161.sparc.rpm 38bb40e8bdfd55387f0e25407d4e5cbd source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.0/zq1/syslogd-1.3.33-161.src.rpm 2017cbca57305092c0a912b77c2411dd AXP Alpha Platform: SuSE-6.4 ftp://ftp.suse.com/pub/suse/axp/update/6.4/a1/syslogd-1.3.33-162.alpha.rpm 419ea3172f4532f77c4fc5907de345f2 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.4/zq1/syslogd-1.3.33-162.src.rpm 44cb992c94dffff0d31b65a0938fc1cc SuSE-6.3 ftp://ftp.suse.com/pub/suse/axp/update/6.3/a1/syslogd-1.3.33-161.alpha.rpm 84cfb8fa2e471baadf96eae1d3be1d0a source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.3/zq1/syslogd-1.3.33-161.src.rpm 23ee4562c993de6943cead4878e73259 SuSE-6.1 ftp://ftp.suse.com/pub/suse/axp/update/6.1/a1/syslogd-1.3.33-161.alpha.rpm 3b04489436b536d3d2e4b4bec6bc5ced source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.1/zq1/syslogd-1.3.33-161.src.rpm ab7edad2685d8d820b0f72b470048e81 PPC Power PC Platform: SuSE-6.4 ftp://ftp.suse.com/pub/suse/ppc/update/6.4/a1/syslogd-1.3.33-161.ppc.rpm 9d588d1d4614d173b60746ae74fc6046 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/zq1/syslogd-1.3.33-161.src.rpm eae3b0cd9b7de4ded453e9151b722b0e ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: This is the updated list of currently known security problems.

SuSE Security Announcement: pam_smb
by draht＠suse.de 13 Sep '00

13 Sep '00

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: pam_smb Date: Wednesday, September 13th, 2000 18:00 MEST Affected SuSE versions: 6.2, 6.3, 6.4, 7.0 Vulnerability Type: remote root compromise Severity (1-10): 8 SuSE default package: no Other affected systems: Linux systems using the pam_smb module Content of this advisory: 1) security vulnerability resolved: pam_smb problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information pam_smb is a package for a PAM (Pluggable Authentication Modules) module that allows Linux/Unix user authentication using a Windows NT server. Versions 1.1.5 and before contain a buffer overflow that would allow a remote attacker to gain root access on the target host, provided that the target host has the module installed and configured. The bug was found by Shaun Clowes <shaun(a)securereality.com.au>, and a new, fixed version of the package was promptly published by Dave Airlie <airlied(a)samba.org>, the author of the pam_smb package. SuSE distributions starting with SuSE-6.2 have the package pam_smb installed if a network server installation configuration has been selected or if the package has been selected manually. To find out if the PAM module is installed, use the command `rpm -q pam_smb'. If the module package is not installed, your host does not exhibit the weakness. If you do not use the pam_smb module, you can safely remove it using the command `rpm -e pam_smb'. SuSE provides update packages with the latest version of pam_smb. If you do use the module, you should upgrade the package as soon as possible. There is currently no easy workaround for this problem other than a package upgrade. Download the update package from locations desribed below and install the package with the command `rpm -Fhv file.rpm'. The md5sum for each file is in the line below. You can verify the integrity of the rpm files using the command `rpm --checksig --nogpg file.rpm', independently from the md5 signatures below. i386 Intel Platform: SuSE-7.0 ftp://ftp.suse.com/pub/suse/i386/update/7.0/n1/pam_smb-1.1.6-0.i386.rpm b5f7c7d92f9f023446a6ca3e73689aee source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/pam_smb-1.1.6-0.src.rpm f56fa744add8ccdc9777f28475106148 SuSE-6.4 ftp://ftp.suse.com/pub/suse/i386/update/6.4/n1/pam_smb-1.1.6-0.i386.rpm 736c2fe5460724461b96d60b057bd4ab source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/pam_smb-1.1.6-0.src.rpm fcfa4609d7d62c6fb0e1f03652dcaf56 SuSE-6.3 ftp://ftp.suse.com/pub/suse/i386/update/6.3/n1/pam_smb-1.1.6-0.i386.rpm d5559e6f3474adcc041f7f8156cde15d source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.3/zq1/pam_smb-1.1.6-0.src.rpm 4fecea0bdf9db5c97d20e0c1e6153663 SuSE-6.2 ftp://ftp.suse.com/pub/suse/i386/update/6.2/n1/pam_smb-1.1.6-0.i386.rpm 73258171e7837d2995b39ebeeb3a87ff source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.2/zq1/pam_smb-1.1.6-0.src.rpm f8f6f03f3c15f2f3c38f30bd97164919 Sparc Platform: SuSE-7.0 ftp://ftp.suse.com/pub/suse/sparc/update/7.0/n1/pam_smb-1.1.6-0.sparc.rpm 9514dd4d6b54208468f0b5aca6ac51e4 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.0/zq1/pam_smb-1.1.6-0.src.rpm 22e8dc3e1b51a0f73e7451edd32dc824 AXP Alpha Platform: SuSE-6.4 ftp://ftp.suse.com/pub/suse/axp/update/6.4/n1/pam_smb-1.1.6-0.alpha.rpm 58547d46f0d19a73f6df6dd60693379f source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.4/zq1/pam_smb-1.1.6-0.src.rpm 5a14499e61e22607efd6f5a6700bf9f8 SuSE-6.3 ftp://ftp.suse.com/pub/suse/axp/update/6.3/n1/pam_smb-1.1.6-0.alpha.rpm b507bcffe74723c5e950af141e17dce5 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.3/zq1/pam_smb-1.1.6-0.src.rpm f9e692675604c2e1fad3567b394e12d6 PPC Power PC Platform: SuSE-6.4 ftp://ftp.suse.com/pub/suse/ppc/update/6.4/n1/pam_smb-1.1.6-0.ppc.rpm 4a098a9308e93f207fa908f6febd7800 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/zq1/pam_smb-1.1.6-0.src.rpm 7e13f60d71ecbda1fc4e3b3765a5ec35 ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - zope Zope is contained in SuSE-7.0, i386 Intel and Sparc Platforms only.

SuSE Security Announcement: apache

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: apache Date: Thursday, September 7th, 2000 20:00 MEST Affected SuSE versions: 6.1, 6.2, 6.3, 6.4, 7.0 Vulnerability Type: remote file viewing Severity (1-10): 2 SuSE default package: yes Other affected systems: none, as of the release date of this advisory Content of this advisory: 1) security vulnerability resolved: apache problem description, discussion, solution and upgrade information 2) credits: @stake 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information The default package selection in SuSE distributions includes apache. The configuration file that comes with the package contains two security relevant errors: a) Starting in SuSE-6.0, a section in apache's configuration file /etc/httpd/httpd.conf reads Alias /cgi-bin-sdb/ /usr/local/httpd/cgi-bin/ This allows remote users to read the cgi script sources of the server, located in /usr/local/httpd/cgi-bin/. b) Starting with SuSE-6.3, the distribution comes with the apache module WebDAV. It is contained in a seperate package, named mod_dav, and it is installed if selected by hand or if a network server configuration has been selected in the installation process. mod_dav is not contained in the default package selection. WebDAV stands for "Web-based Distributed Authoring and Versioning" and allows users to collaboratively edit and manage files on remote web servers (see http://www.webdav.org/ for further details!). If WebDAV is installed, apache will automatically run with the module activated. Opposing the recommendations on the WebDAV homepage under http://www.webdav.org/mod_dav/#security, there is no access control or authentification activated. This should most definitely be considered a security problem. The overall policy wrt activating an installed package will adopt to this conclusion in future releases of the SuSE Linux distribution. Problem a) and b) can be easily solved by changing the relevant parts of apache's configuration file /etc/httpd/httpd.conf: a) Change "Alias /cgi-bin-sdb/ /usr/local/httpd/cgi-bin/" to read: "ScriptAlias /cgi-bin-sdb/ /usr/local/httpd/cgi-bin/" Then, restart apache: `/sbin/init.d/apache restart' b) Change "DAV On" to read: "DAV Off". This removes the problem, regardless of the package being installed or not. Alternatively, you may wish to remove the mod_dav package using the command `rpm -e mod_dav'. Then, restart apache: `/sbin/init.d/apache restart' SuSE strongly recommends to have these changes applied as soon as possible. In addition, SuSE provides an update for the vulnerable misconfigured packages for the case that the admin of a SuSE Linux machine did not change the configuration file yet. Download the update package from locations desribed below and install the package with the command `rpm -Fhv file.rpm'. The md5sum for each file is in the line below.

By supplying a thoughtfully designed string as the visual bell message, local users can obtain root privilege. Exploit information has been published on security forums. The temporary workaround for this problem would be to remove the suid bit from /usr/bin/screen*. This also requires mode changes in the /tmp/screens directory where the pipes for communication between the client and server part of screen are placed upon start of screen. SuSE provides an update for the vulnerable screen package. It is strongly recommended to upgrade to the latest version found on our ftp server as described below. The update packages remove all currently known security problems in the glibc package. Download the update package from locations desribed below and install the package with the command `rpm -Fhv file.rpm'. The md5sum for each file is in the line below. You can verify the integrity of the rpm files using the command `rpm --checksig --nogpg file.rpm', independently from the md5 signatures below. i386 Intel Platform: SuSE-7.0 ftp://ftp.suse.com/pub/suse/i386/update/7.0/ap1/screen-3.9.8-1.i386.rpm 84b6330f0b9ac7600cc5ec53a9dfdbe9 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/screen-3.9.8-1.src.rpm 883d80abf603a4eab2238a4e857301e2 SuSE-6.4 ftp://ftp.suse.com/pub/suse/i386/update/6.4/ap1/screen-3.9.8-0.i386.rpm 52f451ce0c8c49e02311dd16961aa028 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/screen-3.9.8-0.src.rpm a3cb0fb2c90664c6deb986fcbf4e74fd SuSE-6.3 ftp://ftp.suse.com/pub/suse/i386/update/6.3/ap1/screen-3.9.8-0.i386.rpm 2c244140d346b16a3d5fb77e2cf1f860 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.3/zq1/screen-3.9.8-0.src.rpm 2c84eadb44a5694dc3088000fff5ec82 SuSE-6.2 ftp://ftp.suse.com/pub/suse/i386/update/6.2/ap1/screen-3.9.8-0.i386.rpm a72973a281467a1b390453ba2cbf3b59 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.2/zq1/screen-3.9.8-0.src.rpm a379e5b4ca81cf4118002c3064d1c3da SuSE-6.1 ftp://ftp.suse.com/pub/suse/i386/update/6.1/ap1/screen-3.9.8-0.i386.rpm d64479b7ba3740299acf717fe36c3834 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.1/zq1/screen-3.9.8-0.src.rpm e0b08bc5887c40d9f6e3176936c7150b SuSE-6.0 Please use the update packages from the 6.1 directory for SuSE-6.0!

SuSE Security Announcement: shlibs (glibc)
by draht＠suse.de 06 Sep '00

06 Sep '00

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: shlibs (glibc-2.0, glibc-2.1) Date: Wednesday, September 6th, 2000 12:30 MEST Affected SuSE versions: 6.0, 6.1, 6.2, 6.3, 6.4, 7.0 Vulnerability Type: local root compromise Severity (1-10): 9 SuSE default package: yes Other affected systems: all glibc based linux systems, other Un*x systems Content of this advisory: 1) security vulnerability resolved: shlibs (glibc) problem description, discussion, solution and upgrade information 2) pending vulnerabilities, temporary workarounds 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information The glibc implementations in all SuSE distributions starting with SuSE-6.0 have multiple security problems where at least one of them allows any local user to gain root access to the system. a) ld-linux.so.2, the runtime linker, is supposed to clean environment variables that may influence the execution of programs ran by a suid program. Variables of that kind include LD_LIBRARY_PATH and LD_PRELOAD. These variables do not have any effect on the suid application itself since the linker ignores them. However, if the suid program executes another non-suid application without dropping privileges and without cleaning the environment, the LD_* variables would allow an attacker to execute arbitrary code as the effective uid of the calling suid program. There is currently no program in the SuSE distribution known to be susceptible to this problem. b) locale handling portions of the glibc code fails to properly check given environment settings such as the variable LANGUAGE. This could lead to arbitrary code being executed as root, depending on the permissions and ownerships of the program being used for the exploit. c) A bug in the mutex handling code in the shlibs version for SuSE-7.0 could cause multithreaded applications to hang or crash. This has also been fixed. There is only one way to temporarily circumvent the exploit: Disable all suid applications in the system. SuSE provides a updated packages for the vulnerable libraries. It is strongly recommended to upgrade to the latest version found on our ftp server as described below. The update packages remove all currently known security problems in the glibc package. Download the update packages as described below and install the package with the command `rpm -Fhv file.rpm'. The md5sum for each file is in the line below. You can verify the integrity of the rpm files using the command `rpm --checksig --nogpg file.rpm', independently from the md5 signatures below. SPECIAL INSTALL INSTRUCTIONS: Note that the complete update consists of three (3) binary rpm packages and one source rpm package per distribution and platform. libc-*.rpm contains the static libraries, libd is the package for the profiling+debugging version of the libraries. If at all possible, keep your machine calm while you perform the update. Execute the following commands after the rpm update has been applied: /sbin/ldconfig # alternatively, use SuSEconfig /sbin/init u # will restart init to make a clean shutdown # possible once needed. i386 Intel Platform: SuSE-7.0 ftp://ftp.suse.com/pub/suse/i386/update/7.0/a1/shlibs-2.1.3-154.i386.rpm 753176172ebf628c6567c70a9b950933 ftp://ftp.suse.com/pub/suse/i386/update/7.0/d1/libc-2.1.3-154.i386.rpm 0f0696fc359cdb7b13f40a52d6676f09 ftp://ftp.suse.com/pub/suse/i386/update/7.0/d2/libd-2.1.3-154.i386.rpm 4ca3268f91a9294313cf871e9f7cb8b8 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/libc-2.1.3-154.src.rpm a6af3232fe6d474d6309c68469c126ec SuSE-6.4 ftp://ftp.suse.com/pub/suse/i386/update/6.4/a1/shlibs-2.1.3-154.i386.rpm 150dcb3854b066c021c396b4a0fe25e6 ftp://ftp.suse.com/pub/suse/i386/update/6.4/d1/libc-2.1.3-154.i386.rpm 75c9aef75d6e7e4b196c21bb500d00e0 ftp://ftp.suse.com/pub/suse/i386/update/6.4/d2/libd-2.1.3-154.i386.rpm 47fff508b0b67a82356361aa23c8beae source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/libc-2.1.3-154.src.rpm bfeaa4e15ecbe1fea986b710152b5fec SuSE-6.3 ftp://ftp.suse.com/pub/suse/i386/update/6.3/a1/shlibs-2.1.2-47.i386.rpm 8e88f237414a4d8f96131b17267b4d53 ftp://ftp.suse.com/pub/suse/i386/update/6.3/d1/libc-2.1.2-47.i386.rpm 575bb0c94474add7ae02333cbb77cba0 ftp://ftp.suse.com/pub/suse/i386/update/6.3/d2/libd-2.1.2-47.i386.rpm 8728db143b6393a261aa9060d9321345 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.3/zq1/libc-2.1.2-47.src.rpm eea1810dceafe5e7f77b4b5137829834 SuSE-6.2 ftp://ftp.suse.com/pub/suse/i386/update/6.2/a1/shlibs-2.1.1-29.i386.rpm 78360eddc58f3897a14327d2fa214191 ftp://ftp.suse.com/pub/suse/i386/update/6.2/d1/libc-2.1.1-29.i386.rpm 456cad1d8034d40ebbf8337d1308c4de ftp://ftp.suse.com/pub/suse/i386/update/6.2/d2/libd-2.1.1-29.i386.rpm 6dccdf557c6d329b40238a1644368564 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.2/zq1/libc-2.1.1-29.src.rpm cec489c212826cb2dcc65a602da61da3 SuSE-6.1 ftp://ftp.suse.com/pub/suse/i386/update/6.1/a1/shlibs-2000.9.5-0.i386.rpm 7a272e7f15fd2dec69401d4c788de015 ftp://ftp.suse.com/pub/suse/i386/update/6.1/d1/libc-2000.9.5-0.i386.rpm c748944bbe8a55f69478e6ef0bda843a ftp://ftp.suse.com/pub/suse/i386/update/6.1/d2/libd-2000.9.5-0.i386.rpm 7fce2e2e41b62dc985e48ee31f6dac1c source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.1/zq1/libc-2000.9.5-0.src.rpm 77fa60f5a3a10e02460bd1960b1f78f6 Please use the packages from the SuSE-6.1 directory for SuSE-6.0!

SuSE Security Announcement: Netscape
by draht＠suse.de 24 Aug '00

24 Aug '00

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: Netscape, Versions 4.x, possibly others Date: Wednesday, August 23rd, 2000 03:30 MEST Affected SuSE versions: All Vulnerability Type: remote file viewing, remote buffer overflow Severity (1-10): 4, 7 SuSE default package: yes Other affected systems: all linux systems using this package Content of this advisory: 1) security vulnerability resolved: Netscape problem description, discussion, solution and upgrade information 2) Correction/apology for perl thread, pending vulnerabilities, temporary workarounds 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information Two security problems exist in the netscape package as shipped with SuSE Linux distributions. a) Improper verification in Netscape's jpeg processing code can lead to a buffer overflow where data read from the network can overwrite memory. As a result, arbitrary code from a remote origin could be executed. The attack is particularly dangerous since it can penetrate firewall setups. Netscape version 4.74 fixes (fixed) this vulnerability. b) Due to an error in the java implementation in Netscape, it is possible for an attacker to view files and directories with the priviledges of the user running Netscape if the user visits a malisciously crafted webpage. This issue is known as "Brown Orifice" and requires the user to have Java enabled in her browser configuration. Again, this attack can penetrate firewall setups. See http://www.brumleve.com/BrownOrifice for details. Problem a) can be circumvented by disabling the automatic image loading in Netscape's configuration. The temporary workaround for problem b) is to disable Java in Netscape's configuration menu (to protect against other vulnerabilities, disable JavaScript, too!). Both countermeasures may widely be found inacceptable. SuSE provides an updated package for the vulnerable software. It is strongly recommended to upgrade to the latest version found on our ftp server as described below. The update package introduces Netscape version 4.75, including the SuSE-specific libraries that fix some of Netscape's "irregular" behaviour. Please note that Netscape-4.75 is not available for the glibc-2.0-based SuSE Distributions SuSE-6.0 and 6.1 because Netscape doesn't provide any files for this glibc version. For these distributions, we provide Netscape Version 4.74 which fixes problem a) only. Alternatively, the package for the libc5-based SuSE-5.3 distribution can be used as well if the package 'shlibs5' is installed. This is recommended, since the 5.3 package may be faster and more reliable. Download the update package as described below and install the package with the command `rpm -Fhv file.rpm'. The md5sum for each file is in the line below. You can verify the integrity of the rpm files using the command `rpm --checksig --nogpg file.rpm', independently from the md5 signatures below. Due to US-American export restrictions for cryptographical software, we are unable to provide update packages on our US ftp server ftp.suse.com. Instead, the packages can be found on ftp.suse.de. For bandwidth reasons, please use our mirrors or our primary mirror ftp.gwdg.de and follow the directory to your distribution. Example: For SuSE-6.4 use the path ftp://ftp.gwdg.de/pub/linux/suse/6.4_update_de/xap1/netscape.rpm. *********************************************************************** Please note that the path to netscape.rpm in the 6.0 and 6.1 update directories point to Netscape version 4.74 which doesn't fix problem b! See section above! *********************************************************************** Further mirrors can be found at http://www.suse.de/de/support/download/ftp/inland.html, but be advised that not all sites mirror the German part of the update directories. md5sums for the i386 Intel Platform (the only one supported): SuSE Versions 6.2, 6.3, 6.4, 7.0: 70289f88b4c9fc1a9867ba7dac985982 netscape-4.75.glibc21.i386.rpm SuSE Version 5.3 (libc5-based, probably faster, can be used on glibc2-based systems if the package shlibs5 is installed) 679aaf67592244a07733bdabdab67729 netscape-4.75.libc5.i386.rpm SuSE Version 6.0 and 6.1, Netscape-4.74 with incomplete fixes: 4bcc31fe37f7c8d226b437c1daa9b944 netscape-4.74.glibc20.i386.rpm ______________________________________________________________________________ 2) Correction/Apology: In my posting to suse-security(a)suse.de and to bugtraq(a)securityfocus.com about the suidperl thread, Subject: "SuSE Security Announcement: suidperl (perl)", dated 10 Aug 2000, I wrote: "A maliciously implemented feature causes the interpreter to spawn the /bin/mail program to"..." This is a bad and embarrassing mistake because of a confusion about the word "maliciously" in this context - it was meant to read "inconsiderate". I apologize to the perl folks for this mistake. Pending vulnerabilities in SuSE Distributions and Workarounds: This section addresses currently known vulnerabilities in Linux/Unix systems that have not been resolved yet as of the release date of this advisory. - ntop ntop is a network statistics visualization utility which offers graphical analysis of network traffic and other statistics with a web browser. By default, ntop listens on port 3000 and requires no or a commonly known authentication password to view the data. ntop is only installed in network server selections and is not activated by default in SuSE Linux installations. The ntop packages shipped with SuSE Linux did not exhibit the unsafe behaviour when a file like /../../etc/passwd is referenced. However, Thomas Biege has reviewed the source of the package and there are still some potential problems with the package that require a major overhaul of the code. Currently, we recommend to disable or even remove the ntop package (`rpm -e ntop') in an environment where security considerations play a role. More information on ntop can be found in ntop's documentation directory /usr/doc/packages/ntop or /usr/share/doc/packages/ntop for SuSE-7.0. - zope SuSE distributions before 7.0 do not contain zope as a package. An updated package for the freshly released SuSE-7.0 is on the way. - xchat A fix for the URL handler vulnerabilty is in progress and will be released within a few days. There is currently no effective and easy workaround other than removing the package by hand (`rpm -e xchat'). More information on xchat can be found in xchat's documentation directory /usr/doc/packages/xchat or /usr/share/doc/packages/xchat for SuSE-7.0. - minicom SuSE's minicom doesn't exhibit the problem with files created belonging to group uucp because /usr/bin/minicom isn't installed sgid uucp by default. Changing this to 2755 root.uucp (manually and in /etc/permissions) doesn't show any defective behaviour either. - xlockmore: After a review of the relevant part of xlock's code we've found that the format string parsing bug posted by bind(a)SUBTERRAIN.NET on bugtraq on August 15th 2000 is not critical wrt security. xlock drops all privs as soon as it could get hold of the user's encrypted password (which is before it crashes). Other encrypted passwords can't be found in xlock's memory. Since xlock on SuSE distributions runs sgid shadow, it can't dump a core file upon segmentation fault (search /usr/src/linux/kernel/sys.c for "dumpable".) and also can't be traced (/usr/src/linux/arch/i386/kernel/ptrace.c). The bug will be fixed in future releases of the SuSE Linux distribution. The following packages are not contained in SuSE distributions. Therefore, they do not impose any security risks on SuSE systems unless an administrator installed (compiled) the vulnerable software by hand. - FlagShip permissions, from Narrow <nss(a)privacyx.com> on bugtraq dated 10 Aug 2000 - VariCAD permissions with RedHat 6.0, from Narrow <nss(a)privacyx.com> on bugtraq dated 10 Aug 2000 - usermode, from Connectiva on bugtraq, dated 2000-08-10 - gopherd 2.x, from Mike Schiffman <michael.schiffman(a)guardent.com> (guardent) on bugtraq, dated 10 Aug 2000, + Chris Sharp <v9(a)FAKEHALO.ORG> on bugtraq dated 20 Aug 2000. - diskcheck perl script, Connectiva sec. adv. on bugtraq dated 2000-08-10 - Statistics Server 5.02x, overflow, from |Zan <izan(a)DEEPZONE.ORG> on bugtraq, dated 10 Aug 2000 - Helix GNOME Updater (helix-update), versions 0.1 through 0.5, from HELIX CODE, INC., on bugtraq, dated 20 Aug 2000 - Darxite overflows, from Guido Bakker <guidob(a)MAINNET.NL> on bugtraq, dated 21 Aug 2000 - Gnome-Lokkit ports left exposed, from Alan Cox <alan(a)LXORGUK.UKUU.ORG.UK> on bugtraq dated 19 Aug 2000 ______________________________________________________________________________ 3) standard appendix: SuSE runs two security mailing lists to which any interested party may subscribe: suse-security(a)suse.com - general/linux/SuSE security discussion.

SuSE Security Announcement: suidperl (perl)
by draht＠suse.de 10 Aug '00

10 Aug '00

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: perl, all versions Date: Thursday, August 10th, 2000 Affected SuSE versions: 6.0-6.4, 7.0 Vulnerability Type: local root compromise Severity (1-10): 5 SuSE default package: yes, but not configured exploitable. Other affected systems: all linux systems using this package Content of this advisory: 1) security vulnerability resolved: suidperl (local root compromise) problem description, discussion, solution and upgrade information 2) pending vulnerabilities, temporary workarounds (Netscape) 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information suidperl is the perl interpreter for suid perl scripts, a part of the perl package. A maliciously implemented feature causes the interpreter to spawn the /bin/mail program to inform the superuser of its usage, thereby passing on untrusted environment that causes /bin/mail to execute arbitrary commands as user root. SuSE distributions are not susceptible to this problem because /usr/bin/suidperl is mode 755 (not suid) by default. Administrators must explicitly have enabled suidperl by changing the permission modes of the interpreter to 4755 root.root (suid root) for the exploit mechanism to work. In SuSE-Linux, activating suidperl is done by changing one of the files /etc/permissions.(easy|secure) and running SuSEconfig or `chkstat -set /etc/permissions.(easy|secure)', alternatively, depending on the setting of PERMISSION_SECURITY in /etc/rc.config. If SuSEconfig is turned off completely, the administrator of the system is obliged to change the permission modes by hand. The decision to not activate suidperl has been made because security problems were expected in the wild. O/S vendors have provided updated packages for both suidperl and mailx, the package containing /bin/mail. Basically, /bin/mail's fetures are not the origin of the security hole because the hostile environment is passed on by the suidperl interpreter, despite the fact that the interpreter runs suid root. Note: The upcoming SuSE-7.0 distribution _is_ vulnerable to the problem of this advisory if /usr/bin/suidperl is setuid root. However, suidperl is installed with mode 755 after the installation like in older SuSE Linux distributions and therefore can't be exploited without prior manual activation of suidperl by the system administrator. SuSE provides an updated package for the vulnerable software. It is strongly recommended to upgrade to the latest version found on our ftp server as described below. The package removes the mail notification and uses the syslog facility (priority warning) instead. Chose one of the following paths to download the package from our ftp server and install the package with the command `rpm -Fhv file.rpm'. The md5sum for each file is in the line below. You can verify the integrity of the rpm files using the command `rpm --checksig --nogpg file.rpm', independently from the md5 signatures below. i386 Intel Platform: SuSE-7.0 ftp://ftp.suse.com/pub/suse/i386/update/7.0/a1/perl.rpm 01c855f752b835536403c7bcc74d8114 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/perl.spm 16c850efed03cc5bd5b9bff3910dd6e4 SuSE-6.4 ftp://ftp.suse.com/pub/suse/i386/update/6.4/a1/perl.rpm 0640e11ba0b87f0d8a01b4b5dedbb8eb source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/perl.spm a68ade45a65e73805b2276ad35266d46 SuSE-6.3 ftp://ftp.suse.com/pub/suse/i386/update/6.3/a1/perl.rpm 7a3c2adae0c556a7ccb647eaca34e6c7 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.3/zq1/perl.spm 6bc207d360a1349f8f8067a83061f848 SuSE-6.2 ftp://ftp.suse.com/pub/suse/i386/update/6.2/a1/perl.rpm 6403b21d3795def485ad4a577a38c3be source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.2/zq1/perl.spm 47760a9798dc1489ca9fd2ee3a1756f6 SuSE-6.1 ftp://ftp.suse.com/pub/suse/i386/update/6.1/a1/perl.rpm ac14b4fccfb10e5465f377b095621730 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.1/zq1/perl.spm 7d3aec7879fabcac3d2b7e4996340c31 AXP Alpha Platform: SuSE-6.4 ftp://ftp.suse.com/pub/suse/axp/update/6.4/a1/perl.rpm 47853649c4683748558dbb72f759d739 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.4/zq1/perl.spm 5949a68b6126afdca98224cd6ed4be74 SuSE-6.3 ftp://ftp.suse.com/pub/suse/axp/update/6.3/a1/perl.rpm 994804e426adf718df64162c92a1ce84 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.3/zq1/perl.spm 879238a9e443bbe32cc4d421ed9a5d28 SuSE-6.1 ftp://ftp.suse.com/pub/suse/axp/update/6.1/a1/perl.rpm cf2d763fb562a75395c5e613704cbd10 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.1/zq1/perl.spm e0aa5d0c91f474592e56eed2a8b3fae0 PPC Power PC Platform: SuSE-6.4 ftp://ftp.suse.com/pub/suse/ppc/update/6.4/a1/perl.rpm 828a210ef2b3aa462161010d4d19416a source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/zq1/perl.spm 9253498d7c474ad2e9f8dabe576d2c96 ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds This section addresses currently known vulnerabilities in Linux/Unix systems that have not been resolved up to the release date of this advisory. - Netscape, versions from 3.0 to 4.73: The latest version of Netscape is currently being tested. SuSE Netscape rpms contain efficient workarounds against some "morbid" properties of Netscape in order to provide stable packages. These additions are being reworked right now. Also, cryprographical software export regulations require us to wait for the permission to redistribute the netscape package from our US-American ftp server. There are currently two known vulnerabilities in Netscape versions from 3.0 to 4.73: a) a buffer overflow in the jpeg image handling code b) a security flaw in Netscape's Java implementation a) has been fixed in Netscape version 4.74. Updated packages from SuSE will follow very soon. Temporary fix/workaround: problem a) Turn off automatic image loading and do not click on images to trigger the download. This may be a fairly unsatisfying solution. problem b) Turn off Java and JavaScript. - ntop ntop is a network statistics visualization utility which offers graphical analysis of network traffic and other statistics with a web browser. By default, ntop listens on port 3000 and requires no or a commonly known authentication password to view the data. ntop is only installed in network server selections and is not activated by default in SuSE Linux installations. The ntop packages shipped with SuSE Linux did not exhibit the unsafe behaviour when a file like /../../etc/passwd is referenced. ______________________________________________________________________________ 3) standard appendix: SuSE runs two security mailing lists to which any interested party may subscribe: suse-security(a)suse.com - general/linux/SuSE security discussion.
