Synopsis
========

Multiple vulnerabilities have been found in Opera, the worst of which
may allow remote execution of arbitrary code.

Background
==========

Opera is a fast web browser that is available free of charge.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  www-client/opera           < 12.01.1532            >= 12.01.1532

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

Multiple vulnerabilities have been discovered in Opera. Please review
the CVE identifiers and Opera Release Notes referenced below for
details.

Impact
======

A remote attacker could entice a user to open a specially crafted web
page using Opera, possibly resulting in execution of arbitrary code
with the privileges of the process or a Denial of Service condition.
Furthermore, a remote attacker may be able to trick a user into
downloading and executing files, conduct Cross-Site Scripting (XSS)
attacks, spoof the address bar, or have other unspecified impact.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Opera users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=www-client/opera-12.01.1532"
