From security@LINUX-MANDRAKE.COM Tue Jan 30 10:35:16 2001 From: Linux Mandrake Security Team To: BUGTRAQ@SECURITYFOCUS.COM Date: Fri, 26 Jan 2001 11:37:03 -0700 Subject: [BUGTRAQ] MDKSA-2001:015 - exmh update -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ________________________________________________________________________ Linux-Mandrake Security Update Advisory ________________________________________________________________________ Package name: exmh Date: January 26th, 2001 Advisory ID: MDKSA-2001:015 Affected versions: 6.0, 6.1, 7.0, 7.1, 7.2, Corporate Server 1.0.1 ________________________________________________________________________ Problem Description: All versions of exmh prior to 2.3.1 use the /tmp directory for storing temporary files. This was done in an insecure manner as exmh did not check to ensure that nobody placed a symlink with the same name in /tmp in the meantime and thus was vulnerable to a symlink attack. This could lead to a malicious local user being able to overwrite any file writable by the user executing exmh. These updated versions of exmh now use /tmp/username unless TMPDIR or EXMHTMPDIR is set. ________________________________________________________________________ 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 7.2, look for it in "updates/7.2/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.
