MPlayer: GUI filename handling overflow

Background

MPlayer is a media player capable of handling multiple multimedia file formats.

Description

The MPlayer GUI code contains several buffer overflow vulnerabilities, and at least one in the TranslateFilename() function is exploitable.

Impact

By enticing a user to play a file with a carefully crafted filename an attacker could execute arbitrary code with the permissions of the user running MPlayer.

Workaround

To work around this issue, users can compile MPlayer without GUI support by disabling the gtk USE flag. All users are encouraged to upgrade to the latest available version of MPlayer.

Resolution

All MPlayer users should upgrade to the latest version:

 # emerge sync
 
 # emerge -pv ">=media-video/mplayer-1.0_pre4-r7"
 # emerge ">=media-video/mplayer-1.0_pre4-r7"
