From security@linux-mandrake.com Tue Nov 20 19:45:32 2001 From: Linux Mandrake Security Team To: Linux Mandrake Security Announcements Cc: Linux Mandrake Security , Bugtraq Date: Tue, 20 Nov 2001 08:58:40 -0700 Subject: MDKSA-2001:053-1 - gnupg update [The following text is in the "iso-8859-1" character set] [Your display is set for the "US-ASCII" character set] [Some characters may be displayed incorrectly] -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ________________________________________________________________________ Mandrake Linux Security Update Advisory ________________________________________________________________________ Package name: gnupg Advisory Date: November 20th, 2001 Original Advisory Date: May 30th, 2001 Advisory ID: MDKSA-2001:053-1 Affected versions: 7.1, 7.2, 8.0, 8.1, Corporate Server 1.0.1 ________________________________________________________________________ Problem Description: A format string vulnerability exists in gnupg 1.0.5 and previous versions which is fixed in 1.0.6. This vulnerability can be used to invoke shell commands with privileges of the currently logged-in user. Update: The /usr/bin/gpg executable was installed setuid root and setgid root. While being setuid root offers locking pages in physical memory to avoid writing sensitive material to swap and is of benefit, being setgid root provides no benefits and allows users to write to files that have group root access. This update strips the setgid bit from /usr/bin/gpg. ________________________________________________________________________ References: http://archives.indenial.com/hypermail/bugtraq/2001/May2001/0275.html ________________________________________________________________________ Please verify the update prior to upgrading to ensure the integrity of the downloaded package. You can do this with the command: rpm --checksig package.rpm You can get the GPG public key of the Linux-Mandrake Security Team at http://www.linux-mandrake.com/en/security/RPM-GPG-KEYS If you use MandrakeUpdate, the verification of md5 checksum and GPG signature is performed automatically for you.

If you want to upgrade manually, download the updated package from one of our FTP server mirrors and upgrade with "rpm -Fvh *.rpm". You can download the updates directly from one of the mirror sites listed at: http://www.linux-mandrake.com/en/ftp.php3. Updated packages are available in the "updates/[ver]/RPMS/" directory. For example, if you are looking for an updated RPM package for Linux-Mandrake 8.0, look for it in "updates/8.0/RPMS/". Updated source RPMs are available as well, but you generally do not need to download them. Please be aware that sometimes it takes the mirrors a few hours to update.
