Mandrake Linux Security Update Advisory
________________________________________________________________________

Package name: proftpd
Advisory ID: MDKSA-2002:005
Date: January 17th, 2002
Affected versions: 7.2, 8.0, 8.1
________________________________________________________________________

Problem Description:

Matthew S. Hallacy discovered that ProFTPD was not forward resolving
reverse-resolved hostnames. A remote attacker could exploit this to
bypass ProFTPD access controls or have false information logged. Frank
Denis discovered that a remote attacker could send malicious commands
to the ProFTPD server and it would force the process to consume all CPU
and memory resources available to it. This DoS vulnerability could
bring the server down with repeated attacks. Finally, Mattias found a
segmentation fault problem that is considered by the developers to be
unexploitable.

Please verify the update prior to upgrading to ensure the integrity of
the downloaded package. You can do this with the command:
