Topic

An updated fetchmail package that fixes a security bug is now available for
Red Hat Enterprise Linux 2.1, 3, 4 and 5.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

Description

Fetchmail is a remote mail retrieval and forwarding utility intended
for use over on-demand TCP/IP links, like SLIP or PPP connections.

A flaw was found in the way fetchmail processed certain APOP authentication
requests. By sending certain responses when fetchmail attempted to
authenticate against an APOP server, a remote attacker could potentially
acquire certain portions of a user's authentication credentials.
(CVE-2007-1558)

All users of fetchmail should upgrade to this updated package, which
contains a backported patch to correct this issue.

Solution

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use
