Gaim is a full featured instant messaging client which handles a variety of instant messaging protocols.
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.
There is no known workaround at this time.
All Gaim users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-im/gaim-1.1.4"
