Description Jan Lieskovsky 2013-02-11 16:50:26 UTC 
A security flaw was found in the way UPnP implementation of libPurple processed certain UPnP responses (UPnP responses with overly long 'service type', 'public IP address', 'internal IP address', and 'AddRemovePortMapping protocol' values). A remote attacker could send a specially-crafted UPnP response that, when processed by Pidgin, would lead to pidgin executable crash.
