Security Fixes and Rewards

Note: Access to bug details and links may be kept restricted until a majority of users are updated with a fix. We will also retain restrictions if the bug exists in a third party library that other projects similarly depend on, but haven’t yet fixed.

This update includes 50 security fixes. Below, we highlight fixes that were either contributed by external researchers or particularly interesting. Please see the Chromium security page for more information.

We would also like to thank Collin Payne, Christoph Diehl, Sebastian Mauer, Atte Kettunen, and cloudfuzzer for working with us during the development cycle to prevent security bugs from ever reaching the stable channel. $8000 in additional rewards were issued.

As usual, our ongoing internal security work responsible for a wide range of fixes:
[406143] CVE-2014-3175: Various fixes from internal audits, fuzzing and other initiatives (Chrome 37).

Many of the above bugs were detected using AddressSanitizer.

CVE-2014-3177 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-3177):
  Google Chrome before 37.0.2062.94 does not properly handle the interaction
  of extensions, IPC, the sync API, and Google V8, which allows remote
  attackers to execute arbitrary code via unspecified vectors, a different
  vulnerability than CVE-2014-3176.

CVE-2014-3176 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-3176):
  Google Chrome before 37.0.2062.94 does not properly handle the interaction
  of extensions, IPC, the sync API, and Google V8, which allows remote
  attackers to execute arbitrary code via unspecified vectors, a different
  vulnerability than CVE-2014-3177.

CVE-2014-3175 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-3175):
  Multiple unspecified vulnerabilities in Google Chrome before 37.0.2062.94
  allow attackers to cause a denial of service or possibly have other impact
  via unknown vectors, related to the load_truetype_glyph function in
  truetype/ttgload.c in FreeType and other functions in other components.

CVE-2014-3174 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-3174):
  modules/webaudio/BiquadDSPKernel.cpp in the Web Audio API implementation in
  Blink, as used in Google Chrome before 37.0.2062.94, does not properly
  consider concurrent threads during attempts to update biquad filter
  coefficients, which allows remote attackers to cause a denial of service
  (read of uninitialized memory) via crafted API calls.

CVE-2014-3173 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-3173):
  The WebGL implementation in Google Chrome before 37.0.2062.94 does not
  ensure that clear calls interact properly with the state of a draw buffer,
  which allows remote attackers to cause a denial of service (read of
  uninitialized memory) via a crafted CANVAS element, related to
  gpu/command_buffer/service/framebuffer_manager.cc and
  gpu/command_buffer/service/gles2_cmd_decoder.cc.

CVE-2014-3172 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-3172):
  The Debugger extension API in
  browser/extensions/api/debugger/debugger_api.cc in Google Chrome before
  37.0.2062.94 does not validate a tab's URL before an attach operation, which
  allows remote attackers to bypass intended access limitations via an
  extension that uses a restricted URL, as demonstrated by a chrome:// URL.

CVE-2014-3171 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-3171):
  Use-after-free vulnerability in the V8 bindings in Blink, as used in Google
  Chrome before 37.0.2062.94, allows remote attackers to cause a denial of
  service or possibly have unspecified other impact by leveraging improper use
  of HashMap add operations instead of HashMap set operations, related to
  bindings/core/v8/DOMWrapperMap.h and
  bindings/core/v8/SerializedScriptValue.cpp.

CVE-2014-3170 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-3170):
  extensions/common/url_pattern.cc in Google Chrome before 37.0.2062.94 does
  not prevent use of a '\0' character in a host name, which allows remote
  attackers to spoof the extension permission dialog by relying on truncation
  after this character.

CVE-2014-3169 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-3169):
  Use-after-free vulnerability in core/dom/ContainerNode.cpp in the DOM
  implementation in Blink, as used in Google Chrome before 37.0.2062.94,
  allows remote attackers to cause a denial of service or possibly have
  unspecified other impact by leveraging script execution that occurs before
  notification of node removal.

CVE-2014-3168 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-3168):
  Use-after-free vulnerability in the SVG implementation in Blink, as used in
  Google Chrome before 37.0.2062.94, allows remote attackers to cause a denial
  of service or possibly have unspecified other impact by leveraging improper
  caching associated with animation.
