Description Andrej Nemec 2016-06-22 08:57:01 UTC 
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.
