Synopsis
=======
Two vulnerabilities may allow the execution of arbitrary code.

Background
=========
Opera is a multi-platform web browser.

Affected packages
================
    -------------------------------------------------------------------
     Package           /  Vulnerable  /                     Unaffected
    -------------------------------------------------------------------
  1  www-client/opera       < 9.10                             >= 9.10

Description
==========
Christoph Deal discovered that JPEG files with a specially crafted DHT
marker can be exploited to cause a heap overflow. Furthermore, an
anonymous person discovered that Opera does not correctly handle
objects passed to the "createSVGTransformFromMatrix()" function.

Impact
=====
An attacker could potentially exploit the vulnerabilities to execute
arbitrary code with the privileges of the user running Opera by
enticing a victim to open a specially crafted JPEG file or a website
containing malicious JavaScript code.

Workaround
=========
The vendor recommends disabling JavaScript to avoid the
"createSVGTransformFromMatrix" vulnerability. There is no known
workaround for the other vulnerability.

Resolution
=========
All Opera users should update to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/opera-9.10"
