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

The weakness is caused due to an error in restricting the number of
chat requests that a user can initiate to another. This can be
exploited by malicious users to cause Phex to consume large amount of
memory resources by initiating a large number of chat requests to a
victim and then log off.

Successful exploitation causes Phex to become unresponsive.

The weakness has been reported in versions prior to 2.8.6.

SOLUTION:
Update to version 2.8.6.
