A large number of security issues were discovered in the WebKit browser and JavaScript engines. If a user were tricked into viewing a malicious website, a remote attacker could exploit a variety of issues related to web browser security, including cross-site scripting attacks, denial of service attacks, and arbitrary code execution.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote host is affected by the vulnerability described in GLSA-201203-19 (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, a Denial of Service condition,       Universal Cross-Site Scripting, or installation of an extension without       user interaction.
    A remote attacker could also entice a user to install a specially       crafted extension that would interfere with browser-issued web requests.
  Workaround :

    There is no known workaround at this time.

The version of Google Chrome installed on the remote host is earlier than 17.0.963.83 and is, therefore, affected by the following vulnerabilities :

  - An unspecified integer issue exists in libpng.
    (CVE-2011-3045)

  - An error exists related to the extension web request     API that could allow denial of service attacks.
    Note this issue was corrected in a previous, unspecified     release. (CVE-2011-3049)

  - Use-after-free errors exist related to 'first-letter'     handling, CSS cross-fade handling and block splitting.
    (CVE-2011-3050, CVE-2011-3051, CVE-2011-3053)

  - A memory corruption error exists related to WebGL     canvas handling. (CVE-2011-3052)

  - An error exists related to webui privilege isolation.
    (CVE-2011-3054)

  - Installation of unpacked extensions does not use the     application's native user interface for prompts.
    (CVE-2011-3055)

  - A cross-origin violation is possible with 'magic iframe'.
    (CVE-2011-3056)

  - The v8 JavaScript engine could allow invalid reads to     take place. (CVE-2011-3057)
