2. Impact Information

Background

Gaim is a full featured instant messaging client which handles a variety of instant messaging protocols.

Description

Specially crafted SNAC packets sent by other instant-messaging users can cause Gaim to loop endlessly (CAN-2005-0472). Malformed HTML code could lead to invalid memory accesses (CAN-2005-0208 and CAN-2005-0473).

Remote attackers could exploit these issues, resulting in a Denial of Service.
