Title: FAAD2: User-assisted execution of arbitrary code
Date: November 09, 2008
Bugs: #238445
ID: 200811-03

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"
