Description Marcus Meissner 2016-08-02 13:35:04 UTC 
rh#1348871

A denial of service vulnerability exists in the handling of the MXIT protocol in Pidgin. Specially crafted MXIT data sent from the server could potentially result in an out-of-bounds read. A malicious server or man-in-the-middle can send invalid data to trigger this vulnerability.
