Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D
A buffer overflow in FAAD2 might lead to user-assisted execution of
arbitrary code via an MP4 file.
Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
FAAD2 is an open source MPEG-4 and MPEG-2 AAC decoder.
Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/faad2 < 2.6.1-r2 >=3D 2.6.1-r2
Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
The ICST-ERCIS (Peking University) reported a heap-based buffer
overflow in the decodeMP4file() function in frontend/main.c.
Impact
=3D=3D=3D=3D=3D=3D
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
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
There is no known workaround at this time.
Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
All FAAD2 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=3Dmedia-libs/faad2-2.6.1-r2"
