Subject: MDKSA-2001:070 - gdm update
______________________________________________________________________
Mandrake Linux Security Update Advisory
______________________________________________________________________
Package name: gdm
Date: August 20th, 2001
Advisory ID: MDKSA-2001:070
Affected versions: 8.0
______________________________________________________________________
Problem Description:
A buffer overrun exists in the XDMCP handling code used in gdm. By
sending a properly crafted XDMCP message, it is possible for a remote
attacker to execute arbitrary commands as root on the susceptible
machine. By default, XDMCP is disabled in gdm.conf on Mandrake Linux.

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 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.
Mandrake Linux 8.0:

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.
