MPlayer is a media player incuding support for a wide range of audio and video formats.
A buffer overflow has been reported in the DMO_VideoDecoder_Open() function in file loader/dmo/DMO_VideoDecoder.c. Another buffer overflow has been reported in the DS_VideoDecoder_Open() function in file loader/dshow/DS_VideoDecoder.c.
A remote attacker could entice a user to open a specially crafted video file, potentially resulting in the execution of arbitrary code with the privileges of the user running MPlayer.
There is no known workaround at this time.
All MPlayer users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-video/mplayer-1.0.20070321"
