Details

Marco Alvarez found a Denial of Service vulnerability in the Jabber
protocol handler. A remote attacker could exploit this to crash Gaim
by sending specially crafted file transfers to the user.
(CAN-2005-0967)

Stu Tomlinson discovered an insufficient bounds checking flaw in the
URL parser. By sending a message containing a very long URL, a remote
attacker could crash Gaim or execute arbitrary code with the
privileges of the user. This was not possible on all protocols, due to
message length restrictions. Jabber are SILC were known to be
vulnerable. (CAN-2005-1261)

By sending a specially crafted SLP message with an empty body, a
