Google V8 before 3.13.7.5, as used in Google Chrome before 23.0.1271.64, on 64-bit Linux platforms allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted JavaScript code that triggers an out-of-bounds access to an array.

The remote host is affected by the vulnerability described in GLSA-201309-16 (Chromium, V8: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Chromium and V8. Please       review the CVE identifiers and release notes referenced below for       details.
  Impact :

    A context-dependent attacker could entice a user to open a specially       crafted website or JavaScript program using Chromium or V8, possibly       resulting in the execution of arbitrary code with the privileges of the       process or a Denial of Service condition. Furthermore, a remote attacker       may be able to bypass security restrictions or have other, unspecified,       impact.
  Workaround :

    There is no known workaround at this time.

Update to 3.13.7.5. Fixes CVE-2012-5120 CVE-2012-5128 and gets d8 working properly again.
