Description Andrej Nemec 2016-06-22 08:31:17 UTC 
A buffer overflow vulnerability exists in the handling of the MXIT protocol Pidgin. Specially crafted data sent via the server could potentially result in a buffer overflow, potentially resulting in memory corruption. A malicious server or an unfiltered malicious user can send negative length values to trigger this vulnerability.
