- ------------------------------------------------------------------------- Debian Security Advisory DSA-3150-1 security@debian.org http://www.debian.org/security/ Alessandro Ghedini February 02, 2015 http://www.debian.org/security/faq - -------------------------------------------------------------------------
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.
