FAAD2 is an open source MPEG-4 and MPEG-2 AAC decoder.
The ICST-ERCIS (Peking University) reported a heap-based buffer
overflow in the decodeMP4file() function in frontend/main.c.
<impact type="normal">
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.
There is no known workaround at this time.
All FAAD2 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=media-libs/faad2-2.6.1-r2&quot;</code>
