Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200509-01
(MPlayer: Heap overflow in ad_pcm.c)

Sven Tantau discovered a heap overflow in the code handling the
strf chunk of PCM audio streams.

Impact :

An attacker could craft a malicious video or audio file which,
when opened using MPlayer, would end up executing arbitrary code on the
victim's computer with the permissions of the user running MPlayer.

Workaround :

You can mitigate the issue by adding 'ac=-pcm,' to your MPlayer
configuration file (note that this will prevent you from playing
uncompressed audio).

Solution :

All MPlayer users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=media-video/mplayer-1.0_pre7-r1'

Risk factor :

High / CVSS Base Score : 7.5
