lots of "no-login"-users with login shell in /etc/passwd

hi all, i am currently wonderung how come that users like postgres, squid, wwwrun and some other that surely will never need to login have a login shell given in /etc/passwd instead (/bin/bash instead a secure (?) /bin/false). is this only the normal and insecure configuration which can be altered by some script which i don't know? but anyway: is this necessary? is there perhaps a need for a login-shell for the programs that use these users? thanks for your help (and don't be too hard, i'm a newbie *g*) heiko

SuSE Security Announcement: mod_php/mod_php4 (SuSE-SA:2002:007)

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: mod_php, mod_php4 Announcement-ID: SuSE-SA:2002:007 Date: Thursday, Feb 28th 2002 22:00 MET Affected SuSE products: SuSE Linux 6.4, 7.0, 7.1, 7.2, 7.3, SuSE Linux Connectivity Server, SuSE Linux Enterprise Server 7 Vulnerability Type: remote command execution Severity (1-10): 7 SuSE default package: no Other affected systems: systems running php modules in their webservers Content of this advisory: 1) security vulnerability resolved: mod_php, mod_php4 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 e-matters team have found multiple remotely exploitable vulnerabilites in the source code responsible for file upload in the apache modules mod_php and mod_php4 (versions 3 and 4). The weakness can be used to have the webserver execute arbitrary code as supplied by the attacker. A temporary workaround against the problem is to disable the file-upload support using the file_uploads directive in the php.ini file. SuSE Linux versions from 6.4 through 7.1 contained mod_php in versions 3, in addition to php4. Starting with SuSE Linux 7.2, all SuSE products do not contain the php-3 package any more. We provide fixed packages for both major versions of mod_php. We recommend to install the upgrade packages as a permanent solution for the problem. SuSE Linux versions 7.1 and 7.2 contained a mod_php4 package for the roxen http server. If you use the roxen webserver, you should use this package. SuSE Linux starting with versions 7.2 have a package called mod_php4-core. This package is required for the update of mod_php4 - by consequence, you can specify both package filenames in the rpm upgrade command after having downloaded the RPM package files. To find out which packages to download and install, use the following command: rpm -qa | grep php Select the packages to download according to the output of the command above and verify their integrity by the methods listed in section 3) of this announcement. Then, install the package(s) using the command "rpm -Fhv file.rpm" to apply the update. To circumvent problems with package versions depending on each other, specify all package filenames that you downloaded on the commandline of the rpm command. Example: "rpm -Fhv f1.rpm f2.rpm". Our maintenance customers are kindly requested to await the arrival of the packages on the maintenance web while these packages are currently going through extensive testing. The packages will be available tomorrow March 1st. Please use the temporary workaround as described above in the meanwhile. SPECIAL INSTALL INSTRUCTIONS: ============================== After applying the update, the apache webserver should be restarted for the update to become effective. To do this, execute the following command as root: rcapache restart i386 Intel Platform: SuSE-7.3 ftp://ftp.suse.com/pub/suse/i386/update/7.3/n1/mod_php4-core-4.0.6-148.i386…

vulnerabilities in SuSE Distributions and Workarounds: - correction: In our last security announcement SuSE-SA:2002:006 (cups), it is advised to restart a running instance of cupsd after performing the rpm update command to make the package upgrade effective (similar to apache in this announcement). The correct command to accomplish a restart of the cups daemon is "rccups restart". - squid (squid2, squid23, squid-beta packages) Malformed ftp:// style URLs are not treated safely in all squid packages. Our packages are available for most architectures and distributions from our ftp server at the usual location, but the security announcement is waiting for the last packages to complete building and testing. - ucdsnmpd The UCD snmpd contains a variety of security related bugs. The SuSE Security Team have been reviewing the code and the available fixes to ensure that all problems get fixed. The update packages are available at the usual location, but the security announcement is waiting for the last packages to complete building and testing. Regardless of whether you use the fixed or the unfixed packages, it is it is strongly recommended to filter SNMP (TCP and UDP packets with destination to port 161) traffic on your inbound router(s). - ssh/openssh Rumours are spreading that there is a new security breach in implementations of secure shell (ssh). The two implementations shipped with SuSE products have been fixed to our best knowlege, and we are not aware of any security holes in these packages. SuSE Security are investigating this issue and will report any vulnerability found through our announcement list suse-security-announce(a)suse.com (subscription information in section 3 of this security announcement). ______________________________________________________________________________ 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 uninstalled 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 toplevel 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.

SuSE Security Announcement: libz/zlib (SuSE-SA:2002:010) (tandem-announcement, first part)
by Roman Drahtmueller 13 Mar '02

13 Mar '02

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: libz/zlib Announcement-ID: SuSE-SA:2002:010 Date: Monday, Mar 11th 2002 20:45 MET Affected products: 6.4, 7.0, 7.1, 7.2, 7.3 SuSE Linux Database Server SuSE eMail Server III SuSE Firewall SuSE Linux Connectivity Server SuSE Linux Enterprise Server 7 Vulnerability Type: remote command execution Severity (1-10): 8 SuSE default package: yes Other affected systems: systems with recent versions of the compression library Content of this advisory: 1) security vulnerability resolved: libz/zlib 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 zlib compression library is being used by many applications to provide data compression/decompression routines. An error in a decompression routine can corrupt the internal data structures of malloc by a double call to the free() function. If the data processed by the compression library is provided from an untrusted source, it may be possible for an attacker to interfere with the process using the zlib routines. The attack scenario includes a denial of service attack and memory/data disclosure, but it may also be possible to insert arbitrary code into the running program and to execute this code. This update fixes the known problems in the libz/zlib as a permanent fix. There exists no temporary workaround that can efficiently remedy the problem. It is expected that a large range of software is affected. The systems affected are by no means limited to Linux systems or other open-source based operating systems. Note: The libz compression library is being used by several hundred packages in all SuSE products. While the update of the libz package as itself is not problematic, it must be noted that many packages bring their own compression library in their source code. If these packages link against their own version of the libz compression library, their source needs to be fixed as well. Considering the length of a combined Security Announcement, SuSE Security publish a tandem-announcement, consisting of two seperate Security Announcements released in quick succession: SuSE-SA:2002:010 libz/zlib SuSE-SA:2002:011 packages containing libz/zlib Acknowledgements: We thank Owen Taylor who tracked down the bug in the compression library, and to Matthias Clasen for reporting the problem that seemed to be located in the libpng at first. We also thank Mark Adler and Jean-loup Gailly, the authors of the zlib package, for their quick response in the double-free() matter. SPECIAL INSTALL INSTRUCTIONS: =============================== * Installation of the update package: The installation of shared libraries on an actively running system should be done with special care. During the update of the libz package, runtime-linking the shared libraries is likely to fail for processes that execute a new binary with the execve(2) system call. If at all applicable, a system receiving the update should be kept as quiet as possible during the time that the RPM command runs. In doubt, please perform the update in Single User Mode ("init S"). The RPM command must not be interrupted during its operation. After performing the update, the processes that still use the old version of the package must be restarted for the libz upgrade to become effective. If you have performed the update in Single User Mode, this has been done already, and you can safely return to your default runlevel. If in doubt, reboot your system to make sure that the changes are becoming effective. 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. i386 Intel Platform: SuSE-7.3 ftp://ftp.suse.com/pub/suse/i386/update/7.3/a1/libz-1.1.3-597.i386.rpm 799491ca29f9bf95e3e38a73f25abea8 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.3/zq1/libz-1.1.3-597.src.rpm a4071506da6ab39dca5495530028d291 SuSE-7.2 ftp://ftp.suse.com/pub/suse/i386/update/7.2/a1/libz-1.1.3-573.i386.rpm 2197aff65b09fb05b8969ace64d7a4a6 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.2/zq1/libz-1.1.3-573.src.rpm 1694ed149ca946e7ea1cc2da3f14c181 SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/a1/libz-1.1.3-570.i386.rpm c309b104231c596bb81008c38a4e473c source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.1/zq1/libz-1.1.3-570.src.rpm 950c86970cd7c3fc0a30cfab176769ac SuSE-7.0 ftp://ftp.suse.com/pub/suse/i386/update/7.0/a1/libz-1.1.3-571.i386.rpm 8bde6b53a78e5f920080bfa3b6a236a6 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/libz-1.1.3-571.src.rpm 718c36c91cd0f97466cbb2303967d51c SuSE-6.4 ftp://ftp.suse.com/pub/suse/i386/update/6.4/a1/libz-1.1.3-575.i386.rpm 270fc89c1be6854288925a9326f9ca6e source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/libz-1.1.3-575.src.rpm 625ed87653f820f7f65a4a8e045f6cc2 Sparc Platform: SuSE-7.3 ftp://ftp.suse.com/pub/suse/sparc/update/7.3/a1/libz-1.1.3-419.sparc.rpm f890b6d04e9164fc2afa05241c0e94c9 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.3/zq1/libz-1.1.3-419.src.rpm 818d39946dc6c73f425620fba546935c SuSE-7.1 ftp://ftp.suse.com/pub/suse/sparc/update/7.1/a1/libz-1.1.3-406.sparc.rpm ff4ea0da2c5126311f654b2896a70dd9 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.1/zq1/libz-1.1.3-406.src.rpm c3a49ea61f2642d53e29c8a81e07bfd9 SuSE-7.0 ftp://ftp.suse.com/pub/suse/sparc/update/7.0/a1/libz-1.1.3-406.sparc.rpm b9e22f0ff9785ca1d226bd2c5e135909 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.0/zq1/libz-1.1.3-406.src.rpm 25c2b7cd4e20da69b7d806551966bae8 AXP Alpha Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/axp/update/7.1/a1/libz-1.1.3-434.alpha.rpm e8cd8561a1434c36afcccd856d79a483 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.1/zq1/libz-1.1.3-434.src.rpm f7c21774f76fb240205291c4e91ad83c SuSE-7.0 ftp://ftp.suse.com/pub/suse/axp/update/7.0/a1/libz-1.1.3-434.alpha.rpm 15510fc7563e669145d28a69e0e77d8e source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.0/zq1/libz-1.1.3-434.src.rpm 008bc8f743e64e26dccd89baf882b214 SuSE-6.4 ftp://ftp.suse.com/pub/suse/axp/update/6.4/a1/libz-1.1.3-435.alpha.rpm 7d29b7d929e4b36dd6268058bf3c7538 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.4/zq1/libz-1.1.3-435.src.rpm 67a4bd496c7625aaa3049417930e97f8 PPC Power PC Platform: SuSE-7.3 ftp://ftp.suse.com/pub/suse/ppc/update/7.3/a1/libz-1.1.3-432.ppc.rpm b06097a1496ca5fd7b3492c2ab4f7337 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.3/zq1/libz-1.1.3-432.src.rpm 45127ca06e4b019b2e700a0c87c2edb6 SuSE-7.1 ftp://ftp.suse.com/pub/suse/ppc/update/7.1/a1/libz-1.1.3-417.ppc.rpm 783a39b17295e169d344a5f7f1ad7e86 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.1/zq1/libz-1.1.3-417.src.rpm 2ac1e404e8a6723b1eb101b7c7d118e8 SuSE-7.0 ftp://ftp.suse.com/pub/suse/ppc/update/7.0/a1/libz-1.1.3-417.ppc.rpm 24901e0c7ccb6bf5bf17b2af60596d96 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.0/zq1/libz-1.1.3-417.src.rpm f9e6cda577a5007baa84fb9940ec718d SuSE-6.4 ftp://ftp.suse.com/pub/suse/ppc/update/6.4/a1/libz-1.1.3-416.ppc.rpm b3580d5e1b3702c330957bde4422486c source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/zq1/libz-1.1.3-416.src.rpm 32cbca2dbc911da128b5bd1d19789792 ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - Please see the following SuSE Security Announcement SuSE-SA:2002:011 (packages containing libz) for upgrade information regarding packages that bring their own compression library in their source. ______________________________________________________________________________ 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 uninstalled 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 toplevel 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.

RE: [suse-security] strange lines in my /var/log/warn

Martians - logged by the kernel. Most likely produced by a windows system which in spite of all attempts seems incapable of sending network traffic via the correct NIC. If you are using suse Firewall 2 you can turn off martian logging with the following: Open /sbin/SuSEfirewall2 in editor, search for martian and you should see the following line: echo 1 > $i/log_martians 2> /dev/null Change 1 to 0 save and restart your firewall. /etc/rc.d/SuSEfirewall2_final reload It will not log martians anymore. :) See http://www.netsys.com/suse-linux-security/2001/11/msg00159.html for more details. -----Original Message----- From: Linuxdom(a)in-sight.de [mailto:Linuxdom@in-sight.de] Sent: 12 March 2002 16:27 To: suse-security(a)suse.com Subject: [suse-security] strange lines in my /var/log/warn ... and what the hack is this ?

Hallo Ich habe folgendes Netz aufgebaut -------------- ------------ | ADSL Modem |----| INTERNET | -------------- ------------ | ---------- --------------------------- | Switch |--------| Proxy-Server / Firewall | ---------- --------------------------- | ----------------- | Internes Netz | ----------------- Die Clients gehen immer über den Proxy ins Internet. Sie können auch gar nicht anders, da sie pppoe nicht verstehen. Ist das Interne Netz durch die Firewall geschützt, oder wäre es sinnvoller das Modem mit einer 2ten Karte direkt zu Verbinden? Kurt

Re: Problem with SuSE Security Announcement: mod_php/mod_php4 (SuSE-SA:2002:007) ?
by Ralf Zenklusen 12 Mar '02

Hi, We use SuSE7.2 with open_basedir=".:.." and safe_mod = Off. After upgrading it seems that you can no longer upload files. The error message is "Warning*: open_basedir restriction in effect. File is in wrong directory". Even if the script and the file is in the same directory. Has anybody else this problem after applying this patch and open_basedir restriction in use? It seems that the option "open_basedir" has disappeared in the newly installed php.ini ? Is this no longer supported? How can you get a similar result?
