RHSA-2002-216: fetchmail

Vulnerability Assessment Summary
Check for the version of the fetchmail packages

Detailed Explanation for this Vulnerability Assessment

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