Google Chrome before 21.0.1180.89 does not properly perform line breaking, which allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted document.

Chromium was updated to 21.0.1180.88 to fix various bugs and security issues. Security fixes and rewards :

Please see the Chromium security page<http://sites.google.com/a/chromium.org/dev/Home/chromium-security >for more detail. Note that the referenced bugs may be kept private until a majority of our users are up to date with the fix.

The remote host is affected by the vulnerability described in GLSA-201210-07 (Chromium: Multiple vulnerabilities)

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

    A remote attacker could entice a user to open a specially crafted web       site using Chromium, possibly resulting in the execution of arbitrary       code with the privileges of the process, arbitrary file write, a Denial       of Service condition, Cross-Site Scripting in SSL interstitial and       various Universal Cross-Site Scripting attacks.
  Workaround :

    There is no known workaround at this time.

Versions of Google Chrome earlier than 21.0.1180.89 are potentially affected by the following vulnerabilities :

  - An out-of-bounds read error exists related to line-breaking. (CVE-2012-2865)

  - Variable casting errors exist related to 'run-ins' and XSL transformations. (CVE-2012-2866, CVE-2012-2871)

  - An unspecified error exists related to the SPDY protocol that can result in application crashes. (CVE-2012-2867)

  - A unspecified race condition exists related to 'workers' and XHR. (CVE-2012-2868)

  - An unspecified error exists related to stale buffers and URL loading. (CVE-2012-2869)

  - Memory management issues exist related to XPath processing. (CVE-2012-2870)

  - Cross-site scripting is possible during the SSL interstitial process. (CVE-2012-2872)

Successful exploitation of any of these issue could lead to an application crash or even allow arbitrary code execution, subject to the user's privileges.

The version of Google Chrome installed on the remote host is earlier than 21.0.1180.89 and is, therefore, affected by the following vulnerabilities :

  - An out-of-bounds read error exists related to     line-breaking. (CVE-2012-2865)

  - Variable casting errors exist related to 'run-ins' and     XSL transformations. (CVE-2012-2866, CVE-2012-2871)

  - An unspecified error exists related to the SPDY     protocol that can result in application crashes.
    (CVE-2012-2867)

  - A unspecified race condition exists related to     'workers' and XHR. (CVE-2012-2868)

  - An unspecified error exists related to stale buffers     and URL loading. (CVE-2012-2869)

  - Memory management issues exist related to XPath     processing. (CVE-2012-2870)

  - Cross-site scripting is possible during the SSL     interstitial process. (CVE-2012-2872)

Successful exploitation of any of these issues could lead to an application crash or arbitrary code execution, subject to the user's privileges.
