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.
