Description Jan Lieskovsky 2012-06-19 14:50:42 UTC

A code injection flaw was found in the way execute command helper method of Gajim, a Jabber client written in PyGTK, performed sanitization of the 'command' parameter. A remote attacker could provide a specially-crafted link, that when visited by Gajim user would lead to gajim executable crash or, potentially, arbitrary code execution with the privileges of the user running the executable.
