<description>
<p>
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.
</p>
</description>
<impact type="normal">
<p>
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.
</p>
</impact>
<workaround>
<p>
The vendor recommends disabling JavaScript to avoid the
"createSVGTransformFromMatrix" vulnerability. There is no known
workaround for the other vulnerability.
</p>
</workaround>
<resolution>
<p>
All Opera users should update to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=www-client/opera-9.10&quot;</code>
</resolution>
