Description Jan Lieskovsky 2011-12-08 14:15:13 UTC

An out-of heap-based buffer read flaw was found in the way OSCAR (Open System for CommunicAtion in Realtime) protocol plug-in of Pidgin, a Gtk+ based multiprotocol instant messaging client, processed authorization denied messages, containing non-UTF-8 sequences. If a rogue server sent a specially-crafted authorization denied message, it could lead to denial of service (Pidgin crash).
