Synopsis
========

Multiple vulnerabilities have been reported in Chromium and V8, some of

Description
===========

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 web site 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.

The attacker could also entice a user to open a specially crafted web
site using Chromium, possibly resulting in cross-site scripting (XSS),
or an unspecified SPDY certificate checking error.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Chromium users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot -v ">=www-client/chromium-18.0.1025.142"

All V8 users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-lang/v8-3.8.9.16"
