gaim -- AIM/ICQ remote denial of service vulnerability

The GAIM team reports that GAIM is vulnerable to a
denial-of-service vulnerability which can cause GAIM to
freeze:

Certain malformed SNAC packets sent by other AIM or ICQ
users can trigger an infinite loop in Gaim when parsing
the SNAC. The remote user would need a custom client, able
to generate malformed SNACs.
