"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.

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

An input sanitization flaw was found in the way the Pidgin SILC
(Secure Internet Live Conferencing) protocol plug-in escaped certain
UTF-8 characters. A remote attacker could use this flaw to crash
Pidgin via a specially crafted SILC message. (CVE-2011-3594)

Multiple NULL pointer dereference flaws were found in the way the
Pidgin Yahoo! Messenger Protocol plug-in handled malformed YMSG
packets. A remote attacker could use these flaws to crash Pidgin via a
specially crafted notification message. (CVE-2011-1091)

Red Hat would like to thank the Pidgin project for reporting
CVE-2011-1091. Upstream acknowledges Marius Wachtler as the original
reporter of CVE-2011-1091.

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."
