A remote attacker could entice a user to open a specially crafted
MPEG-4 (MP4) file in an application using FAAD2, possibly leading to
the execution of arbitrary code.

<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All FAAD2 users should upgrade to the latest version:
