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"
