Title: CenterICQ Malformed Packet Handling Remote Denial of Service Vulnerability
Severity: MODERATE
Description:
Centericq is a text-mode menu- and window-driven IM interface that supports the ICQ2000, Yahoo!, AIM, IRC, MSN, Gadu-Gadu, and Jabber protocols.
CenterICQ is prone to a remote denial-of-service vulnerability. This issue arises because the application fails to handle exceptional conditions in a proper manner.
The vulnerability presents itself when the client is running on a computer that is directly connected to the Internet and handles an empty packet on the listening port for ICQ messages. 'Enable peer-to-peer communications' must be enabled for this attack to succeed.
A successful attack can cause the client to crash.
