Synopsis
========
A buffer overflow in FAAD2 might lead to user-assisted execution of
arbitrary code via an MP4 file.

Background
==========
FAAD2 is an open source MPEG-4 and MPEG-2 AAC decoder.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/faad2 < 2.6.1-r2 >= 2.6.1-r2

Description
===========
The ICST-ERCIS (Peking University) reported a heap-based buffer
overflow in the decodeMP4file() function in frontend/main.c.

Impact
======
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.

Workaround
==========
There is no known workaround at this time.

Resolution
==========
All FAAD2 users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/faad2-2.6.1-r2"

References
==========
