Description Jan Lieskovsky 2012-03-14 11:50:17 UTC

A denial of service flaw was found in the way MSN protocol plug-in of Pidgin, a Gtk+ based multiprotocol instant messaging client, performed sanitization of certain not UTF-8 encoded text prior its presentation. A remote attacker could send a specially-crafted not UTF-8 encoded text (for example via Offline Instant Message post), which once processed by the Pidgin client of the victim would lead to that Pidgin client abort.
