Description Marcus Meissner 2016-08-02 11:55:03 UTC 
rh#1348848

A buffer overflows vulnerability exists in the handling of the MXIT protocol in Pidgin. Specially crafted MXIT data sent from the server could potentially result in arbitrary code execution. A malicious server or an attacker who intercepts the network traffic can send an invalid size for a packet which will trigger a buffer overflow.

Comment 4 Felix Zhang 2018-06-11 13:43:45 UTC 
With Mxit officially shut down its services in 2016 and pidgin dropped support to the protocol since 2.12. Efforts to backport the fix won't make much sense.
Discussed with Johannes and decided to close this as WONTFIX.
