Description

The remote host is affected by the vulnerability described in GLSA-201312-11 (Win32 Codecs: User-assisted execution of arbitrary code)

A heap-based buffer overflow exists when handling Shockwave Flash files.

Impact :

A remote attacker could entice a user to open a specially crafted Flash
  file using a package linked against Win32 Codecs, possibly resulting in
  execution of arbitrary code with the privileges of the process or a
  Denial of Service condition.

Workaround :

There is no known workaround at this time.
