The XSSAuditor::init function in core/html/parser/XSSAuditor.cpp in the XSS auditor in Blink, as used in Google Chrome before 33.0.1750.117, processes POST requests by using the body of a redirecting page instead of the body of a redirect target, which allows remote attackers to obtain sensitive information via unspecified vectors.

The remote host is affected by the vulnerability described in GLSA-201403-01 (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.
