gaim -- remote crash on some protocols

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

It is possible for a remote user to overflow a static
buffer by sending an IM containing a very large URL
(greater than 8192 bytes) to the Gaim user. This is not
possible on all protocols, due to message length
restrictions. Jabber are SILC are known to be
vulnerable.
