Security Advisory - RHSA-2002:215-09
------------------------------------------------------------------------------
Summary:
Updated fetchmail packages fix vulnerabilities

Updated fetchmail packages are available for Red Hat Linux 6.2, 7, 7.1,
7.2, 7.3, and 8.0 which close a remotely-exploitable vulnerability in
unpatched versions of fetchmail prior to 6.1.0.

Description:
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 execution.

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.
