                   Red Hat Security Advisory

Synopsis:          Moderate: pidgin security update
Advisory ID:       RHSA-2010:0788-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2010-0788.html
Issue date:        2010-10-21
CVE Names:         CVE-2010-1624 CVE-2010-3711 
=====================================================================

1. Summary:

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

The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

2. Relevant releases/architectures:

RHEL Desktop Workstation (v. 5 client) - i386, x86_64
RHEL Optional Productivity Applications (v. 5 server) - i386, x86_64
Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

3. Description:

Pidgin is an instant messaging program which can log in to multiple
accounts on multiple instant messaging networks simultaneously.

Multiple NULL pointer dereference flaws were found in the way Pidgin
handled Base64 decoding. A remote attacker could use these flaws to crash
Pidgin if the target Pidgin user was using the Yahoo! Messenger Protocol,
MSN, MySpace, or Extensible Messaging and Presence Protocol (XMPP) protocol
plug-ins, or using the Microsoft NT LAN Manager (NTLM) protocol for
authentication. (CVE-2010-3711)

A NULL pointer dereference flaw was found in the way the Pidgin MSN
protocol plug-in processed custom emoticon messages. A remote attacker
could use this flaw to crash Pidgin by sending specially-crafted emoticon
messages during mutual communication. (CVE-2010-1624)

Red Hat would like to thank the Pidgin project for reporting these issues.
Upstream acknowledges Daniel Atallah as the original reporter of
CVE-2010-3711, and Pierre Nogus of Meta Security as the original reporter
of CVE-2010-1624.

All Pidgin users should upgrade to these updated packages, which contain
backported patches to resolve these issues. Pidgin must be restarted for
this update to take effect.

4. Solution:

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

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):

589973 - CVE-2010-1624 Pidgin: MSN SLP emoticon DoS (NULL pointer
dereference)
641921 - CVE-2010-3711 Pidgin (libpurple): Multiple DoS (crash) flaws by
processing of unsanitized Base64 decoder values
