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: CVE-2014-3175: Various fixes from internal audits, fuzzing and other initiatives (Chrome 37).

Many of the above bugs were detected using AddressSanitizer.

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2326-1 advisory.

    A use-after-free was discovered in the SVG implementation in Blink. If a user 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-2014-3168)

    A use-after-free was discovered in the DOM implementation in Blink. If a user 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-2014-3169)

    A use-after-free was discovered in V8. If a user 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-2014-3171)

    It was discovered that WebGL clear calls did not interact properly with the state of a draw buffer. If a     user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to     cause a denial of service. (CVE-2014-3173)

    A threading issue was discovered in the Web Audio API during attempts to update biquad filter     coefficients. If a user were tricked in to opening a specially crafted website, an attacker could     potentially exploit this to cause a denial of service. (CVE-2014-3174)

    Multiple security issues were discovered in Chromium. If a user were tricked in to opening a specially     crafted website, an attacker could potentially exploit these to read uninitialized memory, cause a denial     of service via application crash or execute arbitrary code with the privileges of the user invoking the     program. (CVE-2014-3175)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

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.

The version of Google Chrome installed on the remote Mac OS X host is a version prior to 37.0.2062.94. It is, therefore, affected by the following vulnerabilities :

  - Blink contains a use-after-free vulnerability in its SVG     implementation. By using a specially crafted web page, a     remote attacker can cause a denial of service or execute     arbitrary code. (CVE-2014-3168)

  - Blink contains a use-after-free vulnerability in its DOM     implementation. By using a specially crafted web page, a     remote attacker can cause a denial of service or execute     arbitrary code. (CVE-2014-3169)

  - A flaw exists in the 'url_pattern.cc' file that does not     prevent the use of NULL characters '\0' in a host name.
    A remote attacker can use this to spoof the extension     permission dialogue by relying on truncation after this     character. (CVE-2014-3170)

  - Blink contains a use-after-free vulnerability in its V8     bindings. By using improper HashMap add operations, a     remote attacker can cause a denial of service or execute     arbitrary code. (CVE-2014-3171)

  - The Debugger extension API does not properly a validate     a tab's URL before attaching. A remote attacker can     therefore bypass access limitations by means of an     extension that uses a restricted URL. (CVE-2014-3172)

  - A flaw exists in the WebGL implementation where clear     calls do not interact properly with the draw buffer. By     using a specially crafted CANVAS element, a remote     attacker can cause a denial of service. (CVE-2014-3173)

  - A flaw exists in the Blink Web Audio API implementation     in how it updates biquad filter coefficients when there     are concurrent threads. By using specially crafted API     calls, a remote attacker can cause a denial of service.
    (CVE-2014-3174)

  - Flaws exist in the 'load_truetype_glyph' function and     other unspecified functions which can be exploited by a     remote attacker to cause a denial of service or other     impact. (CVE-2014-3175)

  - Flaws exist related to the interaction of the IPC, Sync     API, and V8 extensions. A remote attacker can exploit     these to bypass the sandbox and execute arbitrary code.
    (CVE-2014-3176, CVE-2014-3177)

  - Flaws exist related to the interaction of the IPC, Sync     API, and V8 extensions. A remote attacker can exploit     these to bypass the sandbox and execute arbitrary code.
