RHEL 2.1 : fetchmail (RHSA-2002:216)

high Nessus Plugin ID 12327

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 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.

Solution

Update the affected fetchmail and / or fetchmailconf packages.
