"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 AOL Open System
for Communication in Realtime (OSCAR) protocol plug-in in Pidgin, used
by the AOL ICQ and AIM instant messaging systems, escaped certain
UTF-8 characters. A remote attacker could use this flaw to crash
Pidgin via a specially crafted OSCAR message. (CVE-2011-4601)

Multiple NULL pointer dereference flaws were found in the Jingle
extension of the Extensible Messaging and Presence Protocol (XMPP)
protocol plug-in in Pidgin. A remote attacker could use these flaws to
crash Pidgin via a specially crafted Jingle multimedia message.
(CVE-2011-4602)

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."
