Details

Updated Pidgin packages that fix a security issue and address a bug are now
available for Red Hat Enterprise Linux 3, 4, and 5.

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

Pidgin is a multi-protocol Internet Messaging client.

An integer overflow flaw was found in Pidgin's MSN protocol handler. If a
user received a malicious MSN message, it was possible to execute arbitrary
code with the permissions of the user running Pidgin. (CVE-2008-2927)

Note: the default Pidgin privacy setting only allows messages from users in
the buddy list. This prevents arbitrary MSN users from exploiting this
flaw.

This update also addresses the following bug:

* when attempting to connect to the ICQ network, Pidgin would fail to
connect, present an alert saying the "The client version you are using is
too old", and de-activate the ICQ account. This update restores Pidgin's
ability to connect to the ICQ network.

All Pidgin users should upgrade to these updated packages, which contain
backported patches to resolve these issues.

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
