Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2009-1139.html
Issue date:        2009-07-02
CVE Names:         CVE-2009-1889 
=====================================================================

1. Summary:

Updated pidgin packages that fix one security issue and one bug 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.

2. Relevant releases/architectures:

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

3. 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.

A denial of service flaw was found in the Pidgin OSCAR protocol
implementation. If a remote ICQ user sent a web message to a local Pidgin
user using this protocol, it would cause excessive memory usage, leading to
a denial of service (Pidgin crash). (CVE-2009-1889)

These updated packages also fix the following bug:

* the Yahoo! Messenger Protocol changed, making it incompatible (and
unusable) with Pidgin versions prior to 2.5.7. This update provides Pidgin
2.5.8, which implements version 16 of the Yahoo! Messenger Protocol, which
resolves this issue.

Note: These packages upgrade Pidgin to version 2.5.8. 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
these issues. Pidgin must be restarted for this update to take effect.

4. 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
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/):

508271 - pidgin Yahoo protocol 16 [rhel-4.8.z]
508272 - pidgin Yahoo protocol 16 [rhel-5.3.z]
508738 - CVE-2009-1889 pidgin: DoS via specially-crafted ICQWebMessage
