Description Tomas Hoger 2010-07-22 08:01:06 UTC

Mark Doliner, upstream pidgin/libpurple developer, discovered a NULL pointer dereference flaw in the way libpurple handled certain malformed X-Status messages in ICQ/Oscar protocol.  This flaw could allow remote attacker to crash victim's instant messenger application using libpurple such as pidgin.

This issue only affected pidgin/libpurple versions 2.7.x and was fixed in upstream version 2.7.2.
