                Mandrake Linux Security Update Advisory
________________________________________________________________________

Package name:           util-linux
Date:                   November 1st, 2001
Advisory ID:            MDKSA-2001:084

Affected versions:      8.0, 8.1
________________________________________________________________________

Problem Description:

 Tarhon-Onu Victor found a problem in /bin/login's PAM implementation.
 It stored the value of a static pwent buffer across PAM calls, and when
 used with some PAM modules in non-default configurations (ie. using
 pam_limits), it would overwrite the buffer and cause the user to get
 the credentials of another user.  Thanks to Olaf Kirch for providing
 the patch to fix the problem.

You can get the GPG public key of the Mandrake Linux 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.

To upgrade automatically, use MandrakeUpdate.

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
Mandrake Linux 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.
