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).
