Severity:	normal
Title:	FAAD2: User-assisted execution of arbitrary code
Date:	11/09/2008
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	Architecture(s)
media-libs/faad2	< 2.6.1-r2	>= 2.6.1-r2	All supported architectures

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"
