Heap-based buffer overflow in the FFmpegVideoDecoder::GetVideoBuffer function in media/filters/ffmpeg_video_decoder.cc in Google Chrome before 35.0.1916.153 allows remote attackers to cause a denial of service or possibly have unspecified other impact by leveraging VideoFrame data structures that are too small for proper interaction with an underlying FFmpeg library.

The remote host is affected by the vulnerability described in GLSA-201408-16 (Chromium: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Chromium. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could conduct a number of attacks which include: cross       site scripting attacks, bypassing of sandbox protection,  potential       execution of arbitrary code with the privileges of the process, or cause       a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

Chromium was updated to version 36.0.1985.125. New Functionality :

  - Rich Notifications Improvements

  - An Updated Incognito / Guest NTP design

  - The addition of a Browser crash recovery bubble

  - Chrome App Launcher for Linux

  - Lots of under the hood changes for stability and     performance Security Fixes (bnc#887952,bnc#887955) :

  - CVE-2014-3160: Same-Origin-Policy bypass in SVG

  - CVE-2014-3162: Various fixes from internal audits,     fuzzing and other initiatives and 24 more fixes for     which no description was given. Packaging changes :

  - Switch to newer method to retrieve toolchain packages.
    Dropping the three naclsdk_*tgz files. Everything is now     included in the toolchain_linux_x86.tar.bz2 tarball

  - Add Courgette.tar.xz as that the build process now     requires some files from Courgette in order to build     succesfully. This does not mean that Courgette is     build/delivered.

Includes also an update to Chromium 35.0.1916.153 Security fixes (bnc#882264,bnc#882264,bnc#882265,bnc#882263) :

(CVE-2014-1742, CVE-2014-1743)

An integer overflow bug was discovered in Chromium.

(CVE-2014-1744)

An out-of-bounds read was discovered in Chromium. If a user were tricked in to opening a specially crafter website, an attacker could potentially exploit this to cause a denial of service via application crash. (CVE-2014-1746)

It was discovered that Blink allowed scrollbar painting to extend in to the parent frame in some circumstances. An attacker could potentially exploit this to conduct clickjacking attacks via UI redress. (CVE-2014-1748)

An integer underflow was discovered in Blink. If a user were tricked in to opening a specially crafter website, an attacker could potentially exploit this to cause a denial of service via renderer crash or execute arbitrary code with the privileges of the sandboxed render process. (CVE-2014-3152)

A use-after-free was discovered in Chromium. If a use were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via renderer crash or execute arbitrary code with the privileges of the sandboxed render process. (CVE-2014-3154)

A security issue was discovered in the SPDY implementation. An attacker could potentially exploit this to cause a denial of service via application crash or execute arbitrary code with the privileges of the user invoking the program. (CVE-2014-3155)

A heap overflow was discovered in Chromium. If a use were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via renderer crash or execute arbitrary code with the privileges of the sandboxed render process. (CVE-2014-3157)

It was discovered that Blink did not enforce security rules for subresource loading in SVG images. If a user opened a site that embedded a specially crafted image, an attacker could exploit this to log page views. (CVE-2014-3160)

It was discovered that the SpeechInput feature in Blink could be activated without consent or any visible indication. If a user were tricked in to opening a specially crafted website, an attacker could exploit this to eavesdrop on the user. (CVE-2014-3803).

Several vulnerabilities have been discovered in the chromium web browser.

  - CVE-2014-3154     Collin Payne discovered a use-after-free issue in the     filesystem API.

  - CVE-2014-3155     James March, Daniel Sommermann, and Alan Frindell     discovered several out-of-bounds read issues in the SPDY     protocol implementation.

  - CVE-2014-3156     Atte Kettunen discovered a buffer overflow issue in     bitmap handling in the clipboard implementation.

  - CVE-2014-3157     A heap-based buffer overflow issue was discovered in     chromium's ffmpeg media filter.

In addition, this version corrects a regression in the previous update. Support for older i386 processors had been dropped. This functionality is now restored.

- [369621] Medium CVE-2014-3156: Buffer overflow in clipboard. Credit to Atte Kettunen of OUSPG.

- [368980] CVE-2014-3157: Heap overflow in media.

The version of Google Chrome installed on the remote host is a version prior to 35.0.1916.153 and is thus missing fixes for multiple vulnerabilities, some of which can be leveraged for remote code execution:

  - A use-after-free vulnerability in the filesystem API (CVE-2014-3154)

  - Out-of-bounds read in SPDY implementation (CVE-2014-3155)

  - A buffer overflow vulnerability in clipboard (CVE-2014-3156)

  - A heap-based buffer overflow in media (CVE-2014-3157)

The version of Google Chrome installed on the remote Mac OS X host is a version prior to 35.0.1916.153. It is, therefore, affected by the following vulnerabilities :

  - Use-after-free errors exist in the file system API.
    (CVE-2014-3154)

  - An out-of-bounds read error exists related to SPDY.
    (CVE-2014-3155)

  - A buffer overflow error exits related to the clipboard.
    (CVE-2014-3156)

  - A heap overflow error exists related to media handling.
    (CVE-2014-3157)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
