-----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. 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.

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: cups Announcement-ID: SuSE-SA:2002:006 Date: Wednesday, Feb 27th 2002 12:10 MET Affected SuSE versions: 7.1, 7.2, 7.3 Vulnerability Type: remote privilege escalation Severity (1-10): 5 SuSE default package: no Other affected systems: all systems running CUPS Content of this advisory: 1) security vulnerability resolved: CUPS bufferoverflow in IPP 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 We re-release SuSE Security Announcement SuSE-SA:2002:005 with the new announcement ID SuSE-SA:2002:006 due to minor packaging errors that can result in a malfunction of the printing subsystem. The erroneous packages have been removed from the ftp server. The new packages are in place as announced in the URL list below. The well known Common Unix Printing System (CUPS) was found vulnerable to a buffer overflow in the Internet Printing Protocol (IPP) handling code. The buffer overflow could be exploited by a remote attacker as long as their IP address is allowed to connect to the CUPS server. 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. After updateing the RPM package run "rclpd restart" as root to make the package upgrade effective. i386 Intel Platform: SuSE-7.3 ftp://ftp.suse.com/pub/suse/i386/update/7.3/d3/cups-devel-1.1.10-83.i386.rpm 8d5053ad177a11625184d0758487fc44 SuSE-7.3 ftp://ftp.suse.com/pub/suse/i386/update/7.3/n1/cups-1.1.10-83.i386.rpm d13c2a15aec1e32d33e67e3c5dfbfcbe SuSE-7.3 ftp://ftp.suse.com/pub/suse/i386/update/7.3/n1/cups-client-1.1.10-83.i386.r… f6869afd7a3ca8d25094e8beb685be69 SuSE-7.3 ftp://ftp.suse.com/pub/suse/i386/update/7.3/n1/cups-libs-1.1.10-83.i386.rpm cabe0639064f8d8f4e0966b52f11d879 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.3/zq1/cups-1.1.10-83.src.rpm 44565cf9eef0354eda24c79eb6754615 SuSE-7.2 ftp://ftp.suse.com/pub/suse/i386/update/7.2/d3/cups-devel-1.1.6-104.i386.rpm b248ca457d8240380bb5c52a27b18eef SuSE-7.2 ftp://ftp.suse.com/pub/suse/i386/update/7.2/n1/cups-1.1.6-104.i386.rpm 828f470a6fbee50cfc7405c39aa1d81d source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.2/zq1/cups-1.1.6-104.src.rpm 8447e7162c38ecd5f63742de98d80e76 SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/d3/cups-devel-1.1.6-105.i386.rpm 4ea2040b5c7b46b2e55dacd7073ce9ac SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/n2/cups-1.1.6-105.i386.rpm 268428ba6b0470de8ae381552f185420 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.1/zq1/cups-1.1.6-105.src.rpm 93195300593a49fe6236b5abbfca8806 Sparc Platform: SuSE-7.3 ftp://ftp.suse.com/pub/suse/sparc/update/7.3/d3/cups-devel-1.1.10-36.sparc.… 0970928774ba45661812d2e818b9bbb2 SuSE-7.3 ftp://ftp.suse.com/pub/suse/sparc/update/7.3/n1/cups-1.1.10-36.sparc.rpm 4587059b86c2cefd9097d778ec125ab8 SuSE-7.3 ftp://ftp.suse.com/pub/suse/sparc/update/7.3/n1/cups-client-1.1.10-36.sparc… b26a1937a8bd286328ab164e1cc91ebe SuSE-7.3 ftp://ftp.suse.com/pub/suse/sparc/update/7.3/n1/cups-libs-1.1.10-36.sparc.r… afed35a5212b217bab1556e0e5df39e6 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.3/zq1/cups-1.1.10-36.src.rpm bb1662c9b437b0b88c56a39df9b4b6ad SuSE-7.1 ftp://ftp.suse.com/pub/suse/sparc/update/7.1/d3/cups-devel-1.1.6-38.sparc.r… 0a093efb86b0eb024a21ab5532c2f08a SuSE-7.1 ftp://ftp.suse.com/pub/suse/sparc/update/7.1/n2/cups-1.1.6-38.sparc.rpm 69966f1ee23d904a5085d302a49678d6 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.1/zq1/cups-1.1.6-38.src.rpm b4921596bdec11a93da1031c43caa700 AXP Alpha Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/axp/update/7.1/d3/cups-devel-1.1.6-34.alpha.rpm a1883596165edd8b1fa597dcb9e21d70 SuSE-7.1 ftp://ftp.suse.com/pub/suse/axp/update/7.1/n2/cups-1.1.6-34.alpha.rpm 96d90d112b52262dbd01b01aac5b64d3 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.1/zq1/cups-1.1.6-34.src.rpm 2d648e906fc29c64682c7797adbbdcac PPC PowerPC Platform: SuSE-7.3 ftp://ftp.suse.com/pub/suse/ppc/update/7.3/d3/cups-devel-1.1.10-63.ppc.rpm 04d9a84650c335ecc550c4e55e57a576 SuSE-7.3 ftp://ftp.suse.com/pub/suse/ppc/update/7.3/n1/cups-1.1.10-63.ppc.rpm 1776913fc7df901ce37fe3f41ce3fcb8 SuSE-7.3 ftp://ftp.suse.com/pub/suse/ppc/update/7.3/n1/cups-client-1.1.10-63.ppc.rpm 75d676e87d82d58555bf24d3261d0da6 SuSE-7.3 ftp://ftp.suse.com/pub/suse/ppc/update/7.3/n1/cups-libs-1.1.10-63.ppc.rpm 34f744fc2e7b60db32abc89fbda9fbfd source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.3/zq1/cups-1.1.10-63.src.rpm fa19fa9c5e0558d426de857f2bf45ac6 ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - squid A heap overflow in squid's URL constructing functions is fixed and new packages are currently being built. - ucd-snmpd The UCD snmpd contains various security releated bugs. We are currently reviewing the code and available fixes to ensure they all get fixed. Patches will be available as soon as possible. It is strongly recommended to filter SNMP (TCP and UDP packets with destination of port 161) traffic. - hanterm/wmtv The recently reported vulnerabilities in hanterm and wmtv do not affect SuSE installations because they are not installed setuid or setgid. - cipe We are about to prepare kernel update packages that fix a DoS problem in the kernel modules for the cipe encrypted tunneling software. ______________________________________________________________________________ 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.

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. After updateing the packages run "rclpd restart" as root to start the new daemon. i386 Intel Platform: SuSE-7.3 ftp://ftp.suse.com/pub/suse/i386/update/7.3/n1/cups-1.1.10-81.i386.rpm bfb52a55305ac12880b5e59410205a6e source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.3/zq1/cups-1.1.10-81.src.rpm e3d276cb505eaa1bf35946b5c1029562 SuSE-7.3 ftp://ftp.suse.com/pub/suse/i386/update/7.3/n1/cups-client-1.1.10-81.i386.r… 527eeb095abeb0ee0cad95f028a8222b SuSE-7.3 ftp://ftp.suse.com/pub/suse/i386/update/7.3/n1/cups-libs-1.1.10-81.i386.rpm 9a125db90716f71b4fa31cf2ba4180a8 SuSE-7.3 ftp://ftp.suse.com/pub/suse/i386/update/7.3/d3/cups-devel-1.1.10-81.i386.rpm d8457f2c62e7a85e927b615570efa82b SuSE-7.2 ftp://ftp.suse.com/pub/suse/i386/update/7.2/n1/cups-1.1.6-103.i386.rpm 9a6c6b3fcd1dea6504121b76de1615b5 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.2/zq1/cups-1.1.6-103.src.rpm 92c0fc63d6b9c6c299583868f69ac649 SuSE-7.2 ftp://ftp.suse.com/pub/suse/i386/update/7.2/d3/cups-devel-1.1.6-103.i386.rpm a0ed0a207040b6aa6b8080d7e146ce04 SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/n2/cups-1.1.6-102.i386.rpm 488317348075ae50f0d5f5bd9e82b247 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.1/zq1/cups-1.1.6-102.src.rpm 54f3b1bcb3cc727dfcf05514d84c402d SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/d3/cups-devel-1.1.6-102.i386.rpm 6019620534415dd4d09681583ee627a1 Sparc Platform: SuSE-7.3 ftp://ftp.suse.com/pub/suse/sparc/update/7.3/n1/cups-1.1.10-34.sparc.rpm 7777fb032e1c2b45956db2d3ccf9b3c3 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.3/zq1/cups-1.1.10-34.src.rpm 91684561da7f476055c71239b61c549b SuSE-7.3 ftp://ftp.suse.com/pub/suse/sparc/update/7.3/n1/cups-client-1.1.10-34.sparc… 8badff242e1903d7f812bafb0e6a1831 SuSE-7.3 ftp://ftp.suse.com/pub/suse/sparc/update/7.3/n1/cups-libs-1.1.10-34.sparc.r… 355221f9ca9c435a24251915b3384ea2 SuSE-7.3 ftp://ftp.suse.com/pub/suse/sparc/update/7.3/d3/cups-devel-1.1.10-34.sparc.… 60daf45ca8a75237421c8abd27c9f433 SuSE-7.1 ftp://ftp.suse.com/pub/suse/sparc/update/7.1/n2/cups-1.1.6-37.sparc.rpm 063b7953d50ad4b4958541bfaccd270c source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.1/zq1/cups-1.1.6-37.src.rpm d5d5e4bf719ab2eca49cadc9708e0ff3 SuSE-7.1 ftp://ftp.suse.com/pub/suse/sparc/update/7.1/d3/cups-devel-1.1.6-37.sparc.r… 2cbd702f7d978a098ce9c84e3b1cc7ff AXP Alpha Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/axp/update/7.1/n2/cups-1.1.6-33.alpha.rpm 7188e40aac0c097095c2df088a93265d source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.1/zq1/cups-1.1.6-33.src.rpm ac122fe5b1305bab6a8c5904699d4bd5 SuSE-7.1 ftp://ftp.suse.com/pub/suse/axp/update/7.1/d3/cups-devel-1.1.6-33.alpha.rpm ae6685e65e7db1b9afe276d51d6da51a PPC PowerPC Platform: SuSE-7.3 ftp://ftp.suse.com/pub/suse/ppc/update/7.3/n1/cups-1.1.10-60.ppc.rpm 99aa8fcf0f21d5799931953c90435d72 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.3/zq1/cups-1.1.10-60.src.rpm 6e0b6c9e04eb7167b3585aebbc0deb29 SuSE-7.3 ftp://ftp.suse.com/pub/suse/ppc/update/7.3/n1/cups-client-1.1.10-60.ppc.rpm 61f807924b16930166d711c1da8a4cc0 SuSE-7.3 ftp://ftp.suse.com/pub/suse/ppc/update/7.3/n1/cups-libs-1.1.10-60.ppc.rpm 090132d0ae790027382c88a9b331fa9e SuSE-7.3 ftp://ftp.suse.com/pub/suse/ppc/update/7.3/d3/cups-devel-1.1.10-60.ppc.rpm f211da7b5dc400c8e087a6ef8178afd5 SuSE-7.1 ftp://ftp.suse.com/pub/suse/ppc/update/7.1/n2/cups-1.1.6-47.ppc.rpm 52c247f3cbf4836dacec7a767a4fe3c7 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.1/zq1/cups-1.1.6-47.src.rpm 1937730cf78b1c658b430e9525084a93 SuSE-7.1 ftp://ftp.suse.com/pub/suse/ppc/update/7.1/d3/cups-devel-1.1.6-47.ppc.rpm c906d4106d30f1e84133e8d45a857b2d ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - squid A heap overflow in squid's URL constructing functions is fixed and new packages are currently being built. - ucd-snmpd The UCD snmpd contains various security releated bugs. We are currently reviewing the code and available fixes to ensure they all get fixed. Patches will be available as soon as possible. It is strongly recommended to filter SNMP (TCP and UDP packets with destination of port 161) traffic. - hanterm/wmtv The recently reported vulnerabilities in hanterm and wmtv do not affect SuSE installations because they are not installed setuid or setgid. - cipe We are about to prepare kernel update packages that fix a DoS problem in the kernel modules for the cipe encrypted tunneling software. ______________________________________________________________________________ 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. 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.
