Description Jan Lieskovsky 2013-02-11 16:49:49 UTC 
A security flaw was found in the way Lotus Sametime support implementation of Meanwhile protocol plug-in of libPurple normalized overly long Sametime user names. A rogue server could send a specially-crafted Sametime user name that, when processed by Pidgin would lead to pidgin executable crash.
