Google Chrome before 28.0.1500.71 on Mac OS X does not ensure a sufficient source of entropy for renderer processes, which might make it easier for remote attackers to defeat cryptographic protection mechanisms in third-party components via unspecified vectors.

Versions prior to Google Chrome 28.0.1500.71 are potentially affected by the multiple vulnerabilities, the more serious of which are as follows:

  - Several remote code execution vulnerabilities exist due to use-after-free errors in multiple areas. A remote attacker can leverage this to execute arbitrary code in the context of the application. (CVE-2013-2870, CVE-2013-2871, CVE-2013-2873, CVE-2013-2879)

  - Memory corruption vulnerabilities exist which may be exploitable to induce arbitrary code execution. (CVE-2013-2869, CVE-2013-2878, CVE-2013-2875)

  - Information disclosure vulnerabilities exist that may be exploited by remote attackers to obtain information that can aid in further attacks. (CVE-2013-2853, CVE-2013-2874)

  - A security bypass vulnerability exists due to confusion in extensions permissions, which a remote attacker could exploit to bypass intended security restrictions to perform unauthorized actions. (CVE-2013-2876)

The version of Google Chrome installed on the remote host is a version prior to 28.0.1500.71 and is, therefore, affected by multiple vulnerabilities :

  - A vulnerability exists that exposes HTTP in SSL to a     man-in-the-middle attack. (CVE-2013-2853)

  - Block pop-unders in various scenarios. (CVE-2013-2867)

  - An error exists related to an incorrect sync of the     NPAPI extension component. (CVE-2013-2868)

  - An unspecified flaw exists due to a lack of entropy in     renderers. (CVE-2013-2872)

  - Use-after-free errors exist related to network sockets,     input handling, and resource loading. (CVE-2013-2870,     CVE-2013-2871, CVE-2013-2873)

  - A screen data leak error exists related to GL textures.
    (CVE-2013-2874)

  - An extension permission error exists related to     interstitials.  (CVE-2013-2876)

  - Multiple out-of-bounds errors exist related to JPEG2000,     SVG, text handling and XML parsing.  (CVE-2013-2869,     CVE-2013-2875, CVE-2013-2877, CVE-2013-2878)

  - An unspecified error exists when setting up sign-in and     sync. (CVE-2013-2879)

  - The vendor reports various, unspecified errors exist.
    (CVE-2013-2880)
