Package : vlc
CVE ID : CVE-2014-9626 CVE-2014-9627 CVE-2014-9628 CVE-2014-9629
CVE-2014-9630

Fabian Yamaguchi discovered multiple vulnerabilities in VLC, a multimedia
player and streamer:

CVE-2014-9626

The MP4 demuxer, when parsing string boxes, did not properly check
the length of the box, leading to a possible integer underflow when
using this length value in a call to memcpy(). This could allow
remote attackers to cause a denial of service (crash) or arbitrary
code execution via crafted MP4 files.

CVE-2014-9627

The MP4 demuxer, when parsing string boxes, did not properly check
that the conversion of the box length from 64bit integer to 32bit
integer on 32bit platforms did not cause a truncation, leading to
a possible buffer overflow. This could allow remote attackers to
cause a denial of service (crash) or arbitrary code execution via
crafted MP4 files.

CVE-2014-9628

The MP4 demuxer, when parsing string boxes, did not properly check
the length of the box, leading to a possible buffer overflow. This
could allow remote attackers to cause a denial of service (crash)
or arbitrary code execution via crafted MP4 files.

CVE-2014-9629

The Dirac and Schroedinger encoders did not properly check for an
integer overflow on 32bit platforms, leading to a possible buffer
overflow. This could allow remote attackers to cause a denial of
service (crash) or arbitrary code execution.

For the stable distribution (wheezy), these problems have been fixed in
version 2.0.3-5+deb7u2.

For the upcoming stable distribution (jessie), these problems have been
fixed in version 2.2.0~rc2-2.

For the unstable distribution (sid), these problems have been fixed in
version 2.2.0~rc2-2.

We recommend that you upgrade your vlc packages.
