Security Advisory - RHSA-2009:1536-1
------------------------------------------------------------------------------
Summary:
Moderate: pidgin security update

Updated pidgin packages that fix a security issue are now available for Red
Hat Enterprise Linux 4 and 5.

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

Description:
Pidgin is an instant messaging program which can log in to multiple
accounts on multiple instant messaging networks simultaneously. The AOL
Open System for Communication in Realtime (OSCAR) protocol is used by the
AOL ICQ and AIM instant messaging systems.

An invalid pointer dereference bug was found in the way the Pidgin OSCAR
protocol implementation processed lists of contacts. A remote attacker
could send a specially-crafted contact list to a user running Pidgin,
causing Pidgin to crash. (CVE-2009-3615)

These packages upgrade Pidgin to version 2.6.3. Refer to the Pidgin release
notes for a full list of changes: http://developer.pidgin.im/wiki/ChangeLog

All Pidgin users should upgrade to these updated packages, which correct
this issue. Pidgin must be restarted for this update to take effect.
