DESCRIPTION:
A weakness has been reported in Pidgin, which can be exploited by
malicious people to cause a DoS (Denial of Service).

The weakness is caused due to an error when handling certain MSN
direct connection (P2Pv2) packets. This can be exploited to cause a
NULL pointer dereference error and crash the process via specially
crafted packets.

SOLUTION:
Update to version 2.7.9.
