DESCRIPTION:
A vulnerability has been reported in Gaim, which potentially can be
exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error within the

messages.

Successful exploitation may potentially allow execution of arbitrary

crash the application when accepting file transfers and processing a
malformed MSN SLP message.
