-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: lprold Announcement-ID: SuSE-SA:2003:0014 Date: Thursday, Mar 13th 2003 16:00 MET Affected products: 7.1, 7.2, 7.3 SuSE eMail Server 3.1 SuSE eMail Server III SuSE Firewall Adminhost VPN SuSE Linux Admin-CD for Firewall SuSE Firewall on CD 2 - VPN SuSE Firewall on CD 2 SuSE Linux Enterprise Server for S/390 SuSE Linux Connectivity Server SuSE Linux Enterprise Server 7 SuSE Linux Office Server Vulnerability Type: local privilege escalation Severity (1-10): 3 SuSE default package: yes Cross References: Content of this advisory: 1) security vulnerability resolved: buffer overflow in lprm problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds: - ethereal - qpopper - XFree4 - sendmail - apcupsd - snort - file - zlib - vnc 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information The lprm command of the printing package lprold shipped till SuSE 7.3 contains a buffer overflow. This buffer overflow can be exploited by a local user, if the printer system is set up correctly, to gain root privileges. lprold is installed as default package and has the setuid bit set. As a temporary workaround you can disable the setuid bit of lprm by executing the following tasks as root: - add "/usr/bin/lprm root.root 755" to /etc/permissions.local - run 'chkstat -set /etc/permissions.local' Another way would be to just allow trusted users to run lprm by executing the following tasks as root: - add "/usr/bin/lprm root.trusted 4755" to /etc/permissions.local - run 'chkstat -set /etc/permissions.local' Please download the update package for your distribution and verify its integrity by the methods listed in section 3) of this announcement. Then, install the package using the command "rpm -Fhv file.rpm" to apply the update. Our maintenance customers are being notified individually. The packages are being offered to install from the maintenance web.

Both bugs may lead to remote system compromise. New packages are currently being build and will be available soon. - qpopper In version 4.0.x of qpopper a buffer overflow *after* user authen- tication can be exploited to gain a shell on a POP-server machine. New packages are currently being build and will be available soon. - XFree4 A buffer overflow in the Xlib code can be triggered while handling the environment variable XLOCALEDIR. The X version affected is 4.2.0 (SuSE Linux 8.0 and 8.1). We still investigate this issue. - sendmail A correction is necessary to the last SuSE Security Announcement (SuSE-SA:2003:013) about sendmail: The Vulnerability Type must read remote buffer overflow. - apcupsd The control and management daemon for APC UPS systems is vulnerable to remote code execution due to buffer overflow and format string bugs. A dedicated advisory for this issue will be released as soon as all packages are build. - snort snort, a sensor-based Network Intrusion Detection System, was vulnerable to a buffer overflow in it's RPC preprocessor. As a workaround the following line in snort.conf should be commented out and snort should be restarted to disable the RPC-preprocessor: preprocessor rpc_decode: 111 32771 Future version of SuSE Linux will be shipped with a fixed snort package. - file A locally exploitable buffer overflow was found in the file command. New packages are currently being build and will be available soon. - zlib zlib's function gzprintf() is prone to a buffer overflow if its arguments expand to more then Z_PRINTF_BUFSIZE bytes. A fixed version of zlib will be shipped with future SuSE Linux versions. - vnc VNC (Virtual Network Computing) uses a weak cookie generation process which can be exploited by an attacker to bypass authentication. New packages are currently being tested and will be available on our FTP servers soon. ______________________________________________________________________________ 3) standard appendix: authenticity verification, additional information - Package authenticity verification: SuSE update packages are available on many mirror ftp servers all over the world. While this service is being considered valuable and important to the free and open source software community, many users wish to be sure about the origin of the package and its content before installing the package. There are two verification methods that can be used independently from each other to prove the authenticity of a downloaded file or rpm package: 1) md5sums as provided in the (cryptographically signed) announcement. 2) using the internal gpg signatures of the rpm package. 1) execute the command md5sum <name-of-the-file.rpm> after you downloaded the file from a SuSE ftp server or its mirrors. Then, compare the resulting md5sum with the one that is listed in the announcement. Since the announcement containing the checksums is cryptographically signed (usually using the key security(a)suse.de), the checksums show proof of the authenticity of the package. We disrecommend to subscribe to security lists which cause the email message containing the announcement to be modified so that the signature does not match after transport through the mailing list software. Downsides: You must be able to verify the authenticity of the announcement in the first place. If RPM packages are being rebuilt and a new version of a package is published on the ftp server, all md5 sums for the files are useless. 2) rpm package signatures provide an easy way to verify the authenticity of an rpm package. Use the command rpm -v --checksig <file.rpm> to verify the signature of the package, where <file.rpm> is the filename of the rpm package that you have downloaded. Of course, package authenticity verification can only target an un-installed rpm package file. Prerequisites: a) gpg is installed b) The package is signed using a certain key. The public part of this key must be installed by the gpg program in the directory ~/.gnupg/ under the user's home directory who performs the signature verification (usually root). You can import the key that is used by SuSE in rpm packages for SuSE Linux by saving this announcement to a file ("announcement.txt") and running the command (do "su -" to be root): gpg --batch; gpg < announcement.txt | gpg --import SuSE Linux distributions version 7.1 and thereafter install the key "build(a)suse.de" upon installation or upgrade, provided that the package gpg is installed. The file containing the public key is placed at the top-level directory of the first CD (pubring.gpg) and at ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de . - SuSE runs two security mailing lists to which any interested party may subscribe: suse-security(a)suse.com - general/linux/SuSE security discussion. All SuSE security announcements are sent to this list. To subscribe, send an email to <suse-security-subscribe(a)suse.com>. suse-security-announce(a)suse.com - SuSE's announce-only mailing list.

SuSE Security Announcement: sendmail (SuSE-SA:2003:013)

03 Mar '03

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: sendmail, sendmail-tls Announcement-ID: SuSE-SA:2003:013 Date: Monday, March 3rd 2003, 18:10 MET Affected products: 7.1, 7.2, 7.3, 8.0, 8.1 SuSE Linux Database Server, SuSE Linux Enterprise Server 7, 8 SuSE Linux Firewall on CD/Admin host SuSE Linux Connectivity Server SuSE Linux Office Server Vulnerability Type: local privilege escalation Severity (1-10): 7 SuSE default package: yes (until SuSE Linux 8.0 and SLES7) Cross References: http://www.cert.org/advisories/CA-2003-07.html Content of this advisory: 1) security vulnerability resolved: sendmail problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds: - vnc - w3m 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information sendmail is the most widely used mail transport agent (MTA) in the internet. A remotely exploitable buffer overflow has been found in all versions of sendmail that come with SuSE products. These versions include sendmail-8.11 and sendmail-8.12 releases. sendmail is the MTA subsystem that is installed by default on all SuSE products up to and including SuSE Linux 8.0 and the SuSE Linux Enterprise Server 7. The vulnerability is triggered by an email message sent through the sendmail MTA subsystem. In that respect, it is different from commonly known bugs that occur in the context of an open TCP connection. By consequence, the vulnerability also exists if email messages get forwarded over a relay that itself does not run a vulnerable MTA. This specific detail and the wide distribution of sendmail in the internet causes this vulnerability to be considered an error of major severity. The buffer overflow happens on the heap and is known to be exploitable. As of the writing of this announcement, there is no exploit known to exist in the public. Since there is no known workaround for this vulnerability other than using a different MTA, it is strongly recommended to install the update packages as offered at the locations as listed below. We would like to express our gratitude to Eric Allman for notifying SuSE Security of the problem. The vulnerability was discovered by ISS Internet Security Systems, inc. Please download the update package for your distribution and verify its integrity by the methods listed in section 3) of this announcement. Then, install the package using the command "rpm -Fhv file.rpm" to apply the update. Our maintenance customers are being notified individually.

New packages are currently being tested and will be available on our FTP servers soon. - w3m The textbased web-browser w3m does not properly escape HTML tags. A malicious HTML page or img alt attribute may lead to information leakage. New packages will be available soon. ______________________________________________________________________________ 3) standard appendix: authenticity verification, additional information - Package authenticity verification: SuSE update packages are available on many mirror ftp servers all over the world. While this service is being considered valuable and important to the free and open source software community, many users wish to be sure about the origin of the package and its content before installing the package. There are two verification methods that can be used independently from each other to prove the authenticity of a downloaded file or rpm package: 1) md5sums as provided in the (cryptographically signed) announcement. 2) using the internal gpg signatures of the rpm package. 1) execute the command md5sum <name-of-the-file.rpm> after you downloaded the file from a SuSE ftp server or its mirrors. Then, compare the resulting md5sum with the one that is listed in the announcement. Since the announcement containing the checksums is cryptographically signed (usually using the key security(a)suse.de), the checksums show proof of the authenticity of the package. We disrecommend to subscribe to security lists which cause the email message containing the announcement to be modified so that the signature does not match after transport through the mailing list software. Downsides: You must be able to verify the authenticity of the announcement in the first place. If RPM packages are being rebuilt and a new version of a package is published on the ftp server, all md5 sums for the files are useless. 2) rpm package signatures provide an easy way to verify the authenticity of an rpm package. Use the command rpm -v --checksig <file.rpm> to verify the signature of the package, where <file.rpm> is the filename of the rpm package that you have downloaded. Of course, package authenticity verification can only target an un-installed rpm package file. Prerequisites: a) gpg is installed b) The package is signed using a certain key. The public part of this key must be installed by the gpg program in the directory ~/.gnupg/ under the user's home directory who performs the signature verification (usually root). You can import the key that is used by SuSE in rpm packages for SuSE Linux by saving this announcement to a file ("announcement.txt") and running the command (do "su -" to be root): gpg --batch; gpg < announcement.txt | gpg --import SuSE Linux distributions version 7.1 and thereafter install the key "build(a)suse.de" upon installation or upgrade, provided that the package gpg is installed. The file containing the public key is placed at the top-level directory of the first CD (pubring.gpg) and at ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de . - SuSE runs two security mailing lists to which any interested party may subscribe: suse-security(a)suse.com - general/linux/SuSE security discussion. All SuSE security announcements are sent to this list. To subscribe, send an email to <suse-security-subscribe(a)suse.com>. suse-security-announce(a)suse.com - SuSE's announce-only mailing list. Only SuSE's security announcements are sent to this list. To subscribe, send an email to <suse-security-announce-subscribe(a)suse.com>. For general information or the frequently asked questions (faq) send mail to: <suse-security-info(a)suse.com> or <suse-security-faq(a)suse.com> respectively. ===================================================================== SuSE's security contact is <security(a)suse.com> or <security(a)suse.de>.
