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"
