RHEL 2.1 : fetchmail (RHSA-2002:216)

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated Fetchmail packages are available for Red Hat Linux Advanced
Server which close a remotely-exploitable vulnerability in unpatched
versions of Fetchmail prior to 6.1.0.

Fetchmail is a remote mail retrieval and forwarding utility intended
for use over on-demand TCP/IP links such as SLIP and PPP connections.
Two bugs have been found in the header parsing code in versions of
Fetchmail prior to 6.1.0.

The first bug allows a remote attacker to crash Fetchmail by sending a
carefully crafted DNS packet. The second bug allows a remote attacker
to carefully craft an email in such a way that when it is parsed by
Fetchmail a heap overflow occurs, allowing remote arbitrary code

Both of these bugs are only exploitable if Fetchmail is being used in
multidrop mode (using the 'multiple-local-recipients' feature).

All users of Fetchmail are advised to upgrade to the errata packages
containing a backported fix which is not vulnerable to these issues.
