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
