## Description

A denial of service vulnerability exists in the handling of the MXIT
protocol in Pidgin. Specially crafted MXIT data sent via the server could
potentially result in a null pointer dereference. A malicious server or an
attacker who intercepts the network traffic can send invalid data to
trigger this vulnerability and cause a crash.
