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