source JavaScript engine.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------

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 also could
cause a Java applet to run without user confirmation.
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-15.0.874.121"
All V8 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/v8-3.5.10.24"
