privileges of the user invoking the program. (CVE-2011-3947)

Mateusz Jurczyk and Gynvael Coldwind discovered that FFmpeg incorrectly
handled certain malformed DPCM files. If a user were tricked into opening a
crafted DPCM file, an attacker could cause a denial of service via
application crash, or possibly execute arbitrary code with the privileges
of the user invoking the program. (CVE-2011-3951)

Mateusz Jurczyk and Gynvael Coldwind discovered that FFmpeg incorrectly
handled certain malformed KMVC files. If a user were tricked into opening a
crafted KMVC file, an attacker could cause a denial of service via
application crash, or possibly execute arbitrary code with the privileges
of the user invoking the program. (CVE-2011-3952)

It was discovered that FFmpeg incorrectly handled certain malformed H.264
files. If a user were tricked into opening a crafted H.264 file, an

execute arbitrary code with the privileges of the user invoking the
program. (CVE-2012-0851)

It was discovered that FFmpeg incorrectly handled certain malformed ADPCM
files. If a user were tricked into opening a crafted ADPCM file, an
attacker could cause a denial of service via application crash, or possibly
execute arbitrary code with the privileges of the user invoking the

It was discovered that FFmpeg incorrectly handled certain malformed Atrac 3
files. If a user were tricked into opening a crafted Atrac 3 file, an
attacker could cause a denial of service via application crash, or possibly
execute arbitrary code with the privileges of the user invoking the
program. (CVE-2012-0853)

It was discovered that FFmpeg incorrectly handled certain malformed Shorten
files. If a user were tricked into opening a crafted Shorten file, an
attacker could cause a denial of service via application crash, or possibly
execute arbitrary code with the privileges of the user invoking the
program. (CVE-2012-0858)

It was discovered that FFmpeg incorrectly handled certain malformed Vorbis
files. If a user were tricked into opening a crafted Vorbis file, an
attacker could cause a denial of service via application crash, or possibly
execute arbitrary code with the privileges of the user invoking the
program. (CVE-2012-0859)

Fabian Yamaguchi discovered that FFmpeg incorrectly handled certain
malformed VQA files. If a user were tricked into opening a crafted VQA
file, an attacker could cause a denial of service via application crash, or
possibly execute arbitrary code with the privileges of the user invoking
the program. (CVE-2012-0947)

Update instructions

The problem can be corrected by updating your system to the following package versions:
