SuSE Security Announcement: gdm
by thomas＠suse.de 26 May '00

26 May '00

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: gdm <= 2.0beta4-25 Date: Wed May 24 08:35:39 CET 2000 Affected SuSE versions: 6.2-6.4 Vulnerability Type: remote compromise SuSE default package: no Other affected systems: all linux systems using gdm <= 2.0beta4 ______________________________________________________________________________ A security hole was discovered in the package mentioned above. Please update it as soon as possible or disable the service if you are using this software on your SuSE Linux installation(s). Other Linux distributions or operating systems might be affected as well, please contact your vendor for information about this issue. Please note that we provide this information on an "as-is" basis only. There is no warranty whatsoever and no liability for any direct, indirect or incidental damage arising from this information or the installation of the update package. _____________________________________________________________________________ 1. Problem Description The GNOME package includes a xdm replacement called gdm for handling graphical console and network logins. The gdm code, that process' logins over the network, could be tricked into writing data from the network right into the stack. This condition exists while gdm is running with root privileges and before the user is authenticated. 2. Impact An remote adversary could crash gdm or execute his own code, which leads to root compromise of the system running gdm. 3. Solution By default gdm doesn't accept login connection from the network. Older SuSE releases, which include gdm 1.x, allow network logins by default but aren't vulnerable by this bug. If you need the network login feature of gdm, update the package from our FTP server, please. ______________________________________________________________________________ Please verify these md5 checksums of the updates before installing: (For SuSE 6.0, please use the 6.1 updates) AXP: ffb656afe38ee6e5c04789f8fce8b1a8 ftp://ftp.suse.com/pub/suse/axp/update/6.3/gnm2/gdm-2.0beta4-74.alpha.rpm f5c7bf9b8fd133e74481ecd6c0d5678e ftp://ftp.suse.com/pub/suse/axp/update/6.3/zq1/gdm-2.0beta4-74.src.rpm 928d262fd9e8f1ff40e6f84b560daf7b ftp://ftp.suse.com/pub/suse/axp/update/6.4/gnm2/gdm-2.0beta4-74.alpha.rpm 6f8a0cc01b9b37f5d6b7bf93b138afb2 ftp://ftp.suse.com/pub/suse/axp/update/6.4/zq1/gdm-2.0beta4-74.src.rpm i386: 8a8adfa55587b1db0cf9816e7d8839c6 ftp://ftp.suse.com/pub/suse/i386/update/6.2/gnm2/gdm-2.0beta4-72.i386.rpm fea8fda701692bea4fb658edc7a504ea ftp://ftp.suse.com/pub/suse/i386/update/6.2/zq1/gdm-2.0beta4-72.src.rpm be26d14f8693d50002a5462c28a45d5a ftp://ftp.suse.com/pub/suse/i386/update/6.3/gnm2/gdm-2.0beta4-72.i386.rpm bcc226af12ce171d4aa41c6d490d2b8f ftp://ftp.suse.com/pub/suse/i386/update/6.3/zq1/gdm-2.0beta4-72.src.rpm 372583d0633d4d0115e6f3bc8397cf16 ftp://ftp.suse.com/pub/suse/i386/update/6.4/gnm2/gdm-2.0beta4-72.i386.rpm 33896dd68321aa45c837da34547debf5 ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/gdm-2.0beta4-72.src.rpm <p>______________________________________________________________________________ You can find updates on our ftp-Server: ftp://ftp.suse.com/pub/suse/i386/update for Intel processors ftp://ftp.suse.com/pub/suse/axp/update for Alpha processors or try the following web pages for a list of mirrors: http://www.suse.de/ftp.html http://www.suse.com/ftp_new.html Our webpage for patches: http://www.suse.de/patches/index.html Our webpage for security announcements: http://www.suse.de/security If you want to report vulnerabilities, please contact security(a)suse.de ______________________________________________________________________________ SuSE has got two free security mailing list services to which any interested party may subscribe: use-security(a)suse.com - moderated and for general/linux/SuSE security discussions.

-----BEGIN PGP SIGNED MESSAGE----- <p> UPDATE INFORMATION The original announcement pointed to update rpms which were old and did *NOT* fix the vulnerabilities. We apologize for this mistake. ______________________________________________________________________________ SuSE Security Announcement Package: aaabase < 2000.5.2 Date: Tue May 2 21:56:21 CEST 2000 Affected SuSE versions: all Vulnerability Type: remove any local file(s) executing attacker supplied commands as non-root SuSE default package: yes Other affected systems: unknown ______________________________________________________________________________ A security hole was discovered in the package mentioned above. Please update as soon as possible or disable the service if you are using this software on your SuSE Linux installation(s). Other Linux distributions or operating systems might be affected as well, please contact your vendor for information about this issue. Please note that we provide this information on an "as-is" basis only. There is no warranty whatsoever and no liability for any direct, indirect or incidental damage arising from this information or the installation of the update package. _____________________________________________________________________________ 1. Problem Description aaa_base is the basic package which comes with any SuSE Linux installation. Two vulnerabilities have been found: 1) The cron job /etc/cron.daily/aaa_base does a daily checking of files in /tmp and /var/tmp, where old files will be deleted if configured to do so. Please note this this feature is NOT activated by default 2) Some system accounts have their homedirectories set to /tmp by default. These are the users games, firewall, wwwrun and nobody on a SuSE 6.4. 2. Impact 1) If the /tmp cleanup is activated, any file or directory can be deleted by any local user 2) If an attacker creates dot files in /tmp (e.g. bash profiles), these might be executed if someone uses e.g. "su - nobody" to switch to the nobody user. This can lead to a compromise of that userid. This vulnerability is present in several other unix systems as well - please check all! 3. Solution 1) Update the package from our FTP server. 2) The root user will receive a email with the accounts listed which have a homedirectory in /tmp. You have to fix this by hand, because some installations might break if they rely on information saved in the (unsafe) /tmp homedirectory. The email will give more information what to do. ______________________________________________________________________________ Please verify these md5 checksums of the updates before installing: (for SuSE 6.0 please use the 6.1 update rpm) a8204a4929c139e895f3357021647daa ftp://ftp.suse.com/pub/suse/axp/update/6.1/a1/aaa_base-2000.5.2-0.alpha.rpm 5dee42bd0f531922d0b17d859f3d0d0d ftp://ftp.suse.com/pub/suse/axp/update/6.3/a1/aaa_base-2000.5.2-0.alpha.rpm da8c74f80983beecf23baa62eea45142 ftp://ftp.suse.com/pub/suse/i386/update/6.1/a1/aaa_base-2000.5.2-0.i386.rpm 9618ec3ae63f4d80527a8e3b5f610fc1 ftp://ftp.suse.com/pub/suse/i386/update/6.2/a1/aaa_base-2000.5.2-0.i386.rpm db53e002b6be652b31262bf89be0c31a ftp://ftp.suse.com/pub/suse/i386/update/6.4/a1/aaa_base-2000.5.2-0.i386.rpm 488eda289876ba3c14dbffb881dc8726 ftp://ftp.suse.com/pub/suse/ppc/update/6.3/a1/aaa_base-2000.5.2-0.ppc.rpm ______________________________________________________________________________ You can find updates on our ftp-Server: ftp://ftp.suse.com/pub/suse/i386/update for Intel processors ftp://ftp.suse.com/pub/suse/axp/update for Alpha processors or try the following web pages for a list of mirrors: http://www.suse.de/ftp.html http://www.suse.com/ftp_new.html Our webpage for patches: http://www.suse.de/patches/index.html Our webpage for security announcements: http://www.suse.de/security If you want to report vulnerabilities, please contact security(a)suse.de ______________________________________________________________________________ SuSE has got two free security mailing list services to which any interested party may subscribe: use-security(a)suse.com - moderated and for general/linux/SuSE security discussions.
