Description Huzaifa S. Sidhpurwala 2014-01-24 08:59:15 UTC 
A Heap-based buffer overflow was found in the way MXit protocol plugin of pidgin parsed emoticons. A malicious server could provide a specially crafted emoticon value, which could cause an integer overflow leading to a buffer overflow. This could cause pidgin to crash or possibly execute arbitrary code with the permissions of the user running pidgin.
