Description Marcus Meissner 2016-08-02 12:00:19 UTC 
rh#1348878

An exploitable memory corruption vulnerability exists in the handling of the MXIT protocol in Pidgin. Specially crafted MXIT MultiMX message sent via the server can result in an out-of-bounds write leading to memory disclosure and code execution.

Comment 4 Felix Zhang 2018-06-11 13:43:57 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.
