-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: xinetd Announcement-ID: SuSE-SA:2001:022 Date: Friday, June 29th 2001, 13:26:55 CEST Affected SuSE versions: (6.0, 6.1, 6.2), 6.3, 6.4, 7.0, 7.1, 7.2 Vulnerability Type: remote code execution Severity (1-10): 7 SuSE default package: yes Other affected systems: All systems using xinetd Content of this advisory: 1) security vulnerability resolved: xinetd buffer-overflows 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 Zen-parse has reported a bug to Bugtraq which allows remote attackers to overflow a buffer in the logging routine of xinetd. During investigation we found that more problems exist within xinetd. Xinetd provides its own string-handling (snprintf()-like functions) routines and fails to handle length arguments of 0 properly. Instead of an immediate return it assumes 'no limit' for writing characters to the target-buffer. This can lead to overflows and arbitrary remote code-execution. Additionally xinetd now sets the correct umask before starting other deamons. Please update the packages immediately, kill the old deamon and start the new xinetd deamon with the /etc/rc.d/xinetd start command again if you need it running. Regardless of the bugs in xinetd, please make sure you only run as many services as needed. i386 Intel Platform: SuSE-7.2 ftp://ftp.suse.com/pub/suse/i386/update/7.2/n2/xinetd-2.1.8.8p3-139.i386.rpm a8122710a857e49a356b0786c8aad9eb source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.2/zq1/xinetd-2.1.8.8p3-139.src.rpm 90187bd35f931f07ba72b54c16c1549c SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/n2/xinetd-2.1.8.8p3-140.i386.rpm 346868fe76e17d17d87dadbac4c032bb source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.1/zq1/xinetd-2.1.8.8p3-140.src.rpm 6656be9789888da5b1b37dc1aa9c69a9 SuSE-7.0 ftp://ftp.suse.com/pub/suse/i386/update/7.0/n1/xinetd-2.1.8.8p3-140.i386.rpm ff001b856db620213608dac1c88ebfbe source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/xinetd-2.1.8.8p3-140.src.rpm 627d2f09d9d4607f31e1902eee4e0cb5 SuSE-6.4 ftp://ftp.suse.com/pub/suse/i386/update/6.4/n1/xinetd-2.1.8.8p3-139.i386.rpm ef4697d57a6ceb5e6a55bde51268b92a source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/xinetd-2.1.8.8p3-139.src.rpm 1384b48ed19204324d4a8c2f75d3ea20 SuSE-6.3 ftp://ftp.suse.com/pub/suse/i386/update/6.3/n1/xinetd-2.1.8.8p3-141.i386.rpm 3c29917f0688aa7509f98b0a00a38eed source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.3/zq1/xinetd-2.1.8.8p3-141.src.rpm b7f8cc1e5a7d3c2f6c56040c327a4b20 Sparc Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/sparc/update/7.1/n2/xinetd-2.1.8.8p3-89.sparc.r… a78dd53e2da211b8822b4ca86359a6e0 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.1/zq1/xinetd-2.1.8.8p3-89.src.rpm 9b0acb0dacee2962f19057de43d9f421 AXP Alpha Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/axp/update/7.1/n2/xinetd-2.1.8.8p3-96.alpha.rpm bb2b45d56d2cf54733a20561c8a8e440 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.1/zq1/xinetd-2.1.8.8p3-96.src.rpm 60610276aba8c103a43a40ea0366f675 SuSE-7.0 ftp://ftp.suse.com/pub/suse/axp/update/7.0/n1/xinetd-2.1.8.8p3-96.alpha.rpm 1e4f0685f380db64025837685f8e79c2 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.0/zq1/xinetd-2.1.8.8p3-96.src.rpm addfd497500387b4de4e2c77ff226e01 SuSE-6.4 ftp://ftp.suse.com/pub/suse/axp/update/6.4/n1/xinetd-2.1.8.8p3-95.alpha.rpm f39287594d3297d2625f3878be6b7d98 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.4/zq1/xinetd-2.1.8.8p3-95.src.rpm ea727667791cd774a5df8bcb5b8b2870 SuSE-6.3 ftp://ftp.suse.com/pub/suse/axp/update/6.3/n1/xinetd-2.1.8.8p3-95.alpha.rpm 364120a5e0ba13587efba8c082faafa0 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.3/zq1/xinetd-2.1.8.8p3-95.src.rpm 08c540c506809a9a5b080aa21fe97406 PPC Power PC Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/ppc/update/7.1/n2/xinetd-2.1.8.8p3-102.ppc.rpm b73446661fe3f5967acd0242e83fb815 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.1/zq1/xinetd-2.1.8.8p3-102.src.rpm c89cb923d3c837e50e7f2efc2c9708d2 SuSE-7.0 ftp://ftp.suse.com/pub/suse/ppc/update/7.0/n1/xinetd-2.1.8.8p3-101.ppc.rpm 01fec52a269c456636bcda0d8401b639 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.0/zq1/xinetd-2.1.8.8p3-101.src.rpm f91f365e3cbedc3de52aab7667db97b2 SuSE-6.4 ftp://ftp.suse.com/pub/suse/ppc/update/6.4/n1/xinetd-2.1.8.8p3-101.ppc.rpm ed8e343b428fe812502195a15d9c4219 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/zq1/xinetd-2.1.8.8p3-101.src.rpm a340276cec8a5dedcbcd29e199bef6a1 ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - rxvt The rxvt program contains a buffer-overflow which allows an attacker to locally execute arbitrary code under a different group-id. Please update to the newest rxvt packages. - dqs The dsh-program, shipped with the dqs package contains a buffer-overflow which allows local attackers to execute arbitrary code as root. Please update to the newest packages. - pcp A /tmp - race has been found in the pcp package which allows a local attacker to escalate his priviledges. Affected versions: 7.1, 7.2. We thank Mark Goodwin and Keith Owens from SGI who quickly responded to SuSE in this issue and who released a fixed version of the SGI Performance Co-Pilot in response to the security problem. Future SuSE Linux releases will include the most recent version of the package. Workaround: chmod a-s `rpm -ql pcp` /nosuchfile update-package does the same. ______________________________________________________________________________ 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.

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: samba Announcement-ID: SuSE-SA:2001:021 Date: Friday, Jun 29th 2001 14:45 MEST Affected SuSE versions: (6.0, 6.1, 6.2) 6.3, 6.4, 7.0, 7.1, 7.2 Vulnerability Type: possible remote root compromise Severity (1-10): 7 SuSE default package: yes Other affected systems: systems using samba and the %m macro in the samba main config file Content of this advisory: 1) security vulnerability resolved: samba 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 Michal Zalewski discovered that a remote attacker can write to files owned by root if the samba config file /etc/smb.conf contains the %m macro to specify the logfile for logging access to the samba server. The %m macro substitutes the NetBIOS name - improper validation of this name allows an attacker to write to any file in the system. SuSE Linux distributions do not ship a default /etc/smb.conf config file that contains the %m macro. Therefore, SuSE distributions are not vulnerable to the bug in the out-of-the-box state. In addition to the remotely exploitable bug, there exists another vulnerability which is fixed with the update packages we provide below: temporary files are being handled insecurely so that an attacker with local access to the system can increase her privileges. This error was discovered by Marcus Meissner, Caldera. This specific problem has been fixed with the release of the samba-2.0.9 version. samba release version 2.0.8 intended to correct this local problem, but due to an error, 2.0.9 contained the complete fix. Only the 2.0.10 version as offered for the SuSE Linux distributions 6.3, 6.4, 7.0 and 7.1 fixes all known problems in the samba package. For the recently released SuSE-7.2 distribution we provide an update package to the version 2.2.0a. We thank Martin Walter, CC university of Freiburg, for his helpful contribution in debugging the Large File Support (LSF) of the 7.1 package. NOTES: * We have removed the samba packages from the update trees for the 6.0, 6.1 and 6.2 distributions on our ftp-server. These packages would introduce security risks if installed on a host. * The samba source rpm package in distributions after and including 7.0 generates both the samba.rpm and the smbclnt.rpm package. It is recommended to update both packages for these distributions. Please download the update package from locations described below and check the authenticity of the rpm package file using a method as described in section 3 of this security announcement.

Bandwith requirements keep us from moving the server to our German location. For these reasons, crypto-packages for SuSE Linux distributions before SuSE-7.1 can be obtained from the equivalent tree on ftp.suse.de. Distributions after and including SuSE-7.1 have their crypto-packages hosted on ftp.suse.com. This was possible with some efforts to remove all non-free cryptographical algorithms from our packages. - qpopper In our last security announcement (SuSE-SA:2001:020 gpg/gnupg) we announced that we investigate the buffer overflow that has been found in qpopper versions before 4.0.3. SuSE Linux distributions are not affected by this bug because a different version is being used. - dqs dex(a)raza-mexicana.org has found an exploitable buffer overflow bug in the dsh program from the dqs package on SuSE Linux distributions. To workaround the problem, do "chmod -s /usr/bin/dsh" and change the files /etc/permissions* to reflect the change. If you do not need the dqs package, then deinstall it (rpm -e dqs). Packages for most of the supported SuSE Linux distributions are available at the usual location <a href="ftp://ftp.suse.com/pub/suse/<arch">ftp://ftp.suse.com/pub/suse/<arch</a>>/<dist> for download and installation/update. Do not forget to change the files /etc/permissions* to remove the suid-bit from the dsh program. Please note that we will not issue a dedicated security announcement for this specific bug. - pcp Paul Starzetz discovered a security weakness in the setuid root program /usr/share/pcp/bin/pmpost. The common library in pcp trusts the environment that has been supplied by the user, regardless of privileged execution or not. By consequence, a user can specify the configuration file and therefore write to files owned by root. The problem is not based on insecurely following symlinks as stated by Paul Starzetz. The pcp package is not installed by default in SuSE Linux distributions. We have provided update packages for the SuSE Linux distributions version 7.1 and 7.2 that remove the setuid bit from the pmpost binary. Versions before SuSE-7.1 were not affected because the setuid bit was not set. We thank Keith Owens and Mark Goodwin from Silicon Graphics for responding quickly and for publishing a new version of the pcp package which will be included in future releases of the SuSE Linux distribution. For more information see the /usr/share/doc/packages/pcp directory of your SuSE Linux installation after installing the update package, or go to obtained from http://oss.sgi.com/projects/pcp/download . Please note that there will not be a dedicated security announcement for this specific bug. - xinetd A buffer overflow has been found in xinetd, all versions, all SuSE Linux distributions. It may be abused to remotely attack a host running xinetd. The xinetd package is not installed by default in SuSE Linux distributions. Manual interaction must have been applied to run the daemon. Update packages can be found at the usual location on our ftp server. The security announcement for this security problem is underway. - fetchmail (fetchml) New fetchmail packages are available on the ftp server. The packages cure a buffer overflow that can be exploited by sending a victim a specially designed email, waiting for the victim's fetchmail program to pick up the email. We are preparing a security announcement for this problem. - openssh update packages for the openssh package after (and including) SuSE-6.4 are available on our ftp servers ftp.suse.de (for < 7.1) or ftp.suse.com (for >= 7.1). We are currently checking for a non-security related irregularity in sshd's behaviour under faulty setup conditions. - exim SuSE Linux distributions do not contain the exim Mail Transport Agent (See http://www.exim.org/ for details) and are therefore not susceptible to the recently found security-related bugs. - webmin SuSE Linux distributions do not contain the webmin administration web frontend (See http://www.webmin.org/ for details) and are therefore not vulnerable to the recently found security-related problems in the 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.

SuSE Security Announcement: gpg/GnuPG (SuSE-SA:2001:020)

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: gpg/GnuPG Announcement-ID: SuSE-SA:2001:020 Date: Sunday, Jun 3rd 2001 14:00 MEST Affected SuSE versions: 6.3, 6.4, 7.0, 7.1, (7.2) Vulnerability Type: local privilege escalation Severity (1-10): 6 SuSE default package: yes Other affected systems: systems shipping the gpg/GnuPG package Content of this advisory: 1) security vulnerability resolved: gpg 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 GnuPG (the SuSE package is named "gpg") is a powerful encryption and signing program with a widespread usership in the free software world. It is designed to be a replacement for PGP and conforms to the OpenPGP standard. A format string vulnerability in versions of GnuPG before 1.0.6 has been found. The error occurs when gpg encounters a filename suffix that is not ".gpg" and prints the filename without the suffix as a default to the terminal. The bug allows an attacker to execute arbitrary code as the user calling gpg. Werner Koch, the author of the GnuPG package, states that when the "--batch" commandline option is used (such as when verifying rpm packages, see Section 3 of this announcement, or when used in MUAs (Mail User Agent)), the error cannot occur since this option supresses the printout of the filename on the terminal. There is no temporary workaround for the problem except for the "--batch" commandline option to gpg. We recommend to update the gpg package on all systems where it is installed. As an additional reason to update the package, it should be noted that gnupg 1.0.5 (packages were available on our ftp server) fixed some security-related problems, where one of them could allow an attacker with access to your key ring to compute the private key in considerably less time. We thank Werner Koch, the author of the GnuPG program, for quickly responding to the problem and fish stiqz, Synnergy Networks, for finding and communicating the problem to Werner Koch and to the security community. Please download the update package from locations described below and check the authenticity of the rpm package file using a method as described in section 3) of this security announcement. Please note that the packages for the 7.1 distribution are located on the ftp.suse.com ftp server, the packages for older distributions are on ftp.suse.de. The upcoming SuSE Linux Distribution 7.2 has been officially announced and will be available for our customers these days. The gpg package in version 1.0.6 did not make it into the 7.2 distribution. The update package will be available in the update directory shortly. Use the command `rpm -Uhv file.rpm' to apply the update. i386 Intel Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/sec1/gpg-1.0.6-0.i386.rpm 39153126feeddf43a939c89a9b1a33fd source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.1/zq1/gpg-1.0.6-0.src.rpm 318ebedd094da2063ecaf209a9a686be SuSE-7.0 ftp://ftp.suse.de/pub/suse/i386/update/7.0/sec1/gpg-1.0.6-0.i386.rpm b78951d79a8c9593a9baf14963c2eb61 source rpm: ftp://ftp.suse.de/pub/suse/i386/update/7.0/zq1/gpg-1.0.6-0.src.rpm ea2067aacf9fb45d2a94eba066fdc18b SuSE-6.4 ftp://ftp.suse.de/pub/suse/i386/update/6.4/sec1/gpg-1.0.6-1.i386.rpm 6050bffa597965475a4caf0a5c265c23 source rpm: ftp://ftp.suse.de/pub/suse/i386/update/6.4/zq1/gpg-1.0.6-1.src.rpm 320eff2cc72cad2bce555993fbc7cb61 SuSE-6.3 ftp://ftp.suse.de/pub/suse/i386/update/6.3/sec1/gpg-1.0.6-1.i386.rpm 6050bffa597965475a4caf0a5c265c23 source rpm: ftp://ftp.suse.de/pub/suse/i386/update/6.3/zq1/gpg-1.0.6-1.src.rpm 320eff2cc72cad2bce555993fbc7cb61 Sparc Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/sparc/update/7.1/sec1/gpg-1.0.6-0.sparc.rpm 20d3a3d7d65aee48f281edf0ae2f162c source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.1/zq1/gpg-1.0.6-0.src.rpm d827d8e68a306c2d7890a5c113d934d3 SuSE-7.0 ftp://ftp.suse.de/pub/suse/sparc/update/7.0/sec1/gpg-1.0.6-0.sparc.rpm fca18e28c3442b16d7aaf614a5bda269 source rpm: ftp://ftp.suse.de/pub/suse/sparc/update/7.0/zq1/gpg-1.0.6-0.src.rpm 797e4f8410e4e4ba159bfc0e3eb7c06c PPC Power PC Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/ppc/update/7.1/sec1/gpg-1.0.6-0.ppc.rpm 9c4c27fd13e9d27ac712bb37cdbe1972 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.1/zq1/gpg-1.0.6-0.src.rpm f262178a3b3d92c6382a303c3aba728e SuSE-7.0 ftp://ftp.suse.de/pub/suse/ppc/update/7.0/sec1/gpg-1.0.6-0.ppc.rpm 378dea2eb7b63ca376330f10757c042e source rpm: ftp://ftp.suse.de/pub/suse/ppc/update/7.0/zq1/gpg-1.0.6-0.src.rpm a1815320cc4537bd18f4c361880c9f44 SuSE-6.4 ftp://ftp.suse.de/pub/suse/ppc/update/6.4/sec1/gpg-1.0.5-3.ppc.rpm d76adf2f7ab76454b05202df580a0235 source rpm: ftp://ftp.suse.de/pub/suse/ppc/update/6.4/zq1/gpg-1.0.5-3.src.rpm bc18a284bfee16e96a2ff7f6749b4cd1 AXP Alpha Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/axp/update/7.1/sec1/gpg-1.0.6-0.alpha.rpm 68f791f8d03e3afbad5ee12b529ecc3c source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.1/zq1/gpg-1.0.6-0.src.rpm 41a50ddce1b16fd91627ac6b155426f6 SuSE-7.0 ftp://ftp.suse.de/pub/suse/axp/update/7.0/sec1/gpg-1.0.6-0.alpha.rpm 696989a2d730b1dbf3891f6b14c42be3 source rpm: ftp://ftp.suse.de/pub/suse/axp/update/7.0/zq1/gpg-1.0.6-0.src.rpm c76556d46b5de45349c146cb9b65b526 SuSE-6.4 ftp://ftp.suse.de/pub/suse/axp/update/6.4/sec1/gpg-1.0.6-1.alpha.rpm e56719ef69aee3a6758f43317cd205cb source rpm: ftp://ftp.suse.de/pub/suse/axp/update/6.4/zq1/gpg-1.0.6-1.src.rpm 6e54ae31543db2c70a3b47f4916e7964 SuSE-6.3 ftp://ftp.suse.de/pub/suse/axp/update/6.3/sec1/gpg-1.0.6-2.alpha.rpm 55cb31d055cfaa7e96908391b075550e source rpm: ftp://ftp.suse.de/pub/suse/axp/update/6.3/zq1/gpg-1.0.6-2.src.rpm e19e2ae8c07e813ff00e65a618046974 ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - qpopper SuSE Linux distributions after SuSE-7.1 contain the qpopper in version 4.x.y. According to the Changelogs of Qpopper 4.0.3 (See ftp://ftp.qualcomm.com/eudora/servers/unix/popper/) the versions of qpopper before version 4.0.3 contain a buffer overflow. We are currently investigating if this bug is exploitable and which versions of qpopper are affected. We will provide update packages as soon as possible if necessary. Please see our upcoming security announcements (Section 3 of this announcement)! - netscape Netscape before Version 4.77 contains a bug that allows a remote attacker to store JavaScript code in the comment field of GIF files that are contained in a viewed page. This code can be executed. Update packages for the SuSE Linux distributions 6.3, 6.4, 7.0 and 7.1 can be found on our ftp server at ftp://ftp.suse.com/pub/suse/i386/update/7.1/xap1/netscape-4.77-21.i386.rpm 1e2de825b3386d80a3731760b9e7f323 ftp://ftp.suse.com/pub/suse/i386/update/7.0/xap1/netscape-4.77-21.i386.rpm ftp://ftp.suse.com/pub/suse/i386/update/6.4/xap1/netscape-4.77-21.i386.rpm ftp://ftp.suse.com/pub/suse/i386/update/6.3/xap1/netscape-4.77-21.i386.rpm 13f303944c9ac0863591b03c4eb75501 The packages are gpg-signed. See the section above about downloading and verifying rpm packages. The complexity of the netscape browser suggests by nature that more security related problems will be found, we will not issue a dedicated security announcement for the netscape package any more. Security- inclined users may please see the future security announcements in section 2) for information about security related problems with the netscape package. - pine Most of the supported distributions have pine update packages in the update area of the ftp server that update the pine package to version 4.33. Many vulnerabilities have been found in versions before 4.33, and it is recommended to perform the upgrade. Please note that not all packages have been built yet. See the update directory for your distribution (like i386/update/7.0/n1) for pine-4.33 packages. - dqs dex(a)raza-mexicana.org has found an exploitable buffer overflow bug in the dsh program from the dqs package on SuSE Linux distributions. To workaround the problem, do "chmod -s /usr/bin/dsh" and change the files /etc/permissions* to reflect the change. If you do not need the dqs package, then deinstall it (rpm -e dqs). We are working on update packages that fix the problem. - samba Insecure temporary file handling is the cause for a new samba version 2.0.9 that can be found as rpm packages in the n1/ directory of your distribution. It is recommended to install the update package if your users have local shell access to your samba server (this bug is not remotely exploitable). We are currently investigating some oddity in the behaviour of the samba package and will send a security announcement as soon as we have clarified the problems. The problems were present in earlier releases/versions of the samba package as well. By consequence, the installation of the update package is of low risk for the functionality of your system. ______________________________________________________________________________ 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 --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.
