Description Jan Lieskovsky 2012-05-07 09:52:46 UTC

An improper input validation flaw was found in the way MSN protocol plug-in of Pidgin, a Gtk+ based multiprotocol instant messaging client, performed parsing of MSN message payload containing certain characters. If a remote server provided a specially-crafted MSN notification message or remote attacker, being present on the buddy list of the victim, provided a specially-crafted MSN offline instant message, it could lead to pidgin executable crash.
