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: 41c178fc24d9acb2ead1438e837f0325
8.0/RPMS/gdm-2.2.3.2-2.1mdk.i586.rpm 1688432b516b398ad1c20ac80c1d028f

Bug IDs fixed (see https://qa.mandrakesoft.com for more information):
________________________________________________________________________
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.
