[GLSA-200701-08] Opera: Two remote code execution vulnerabilities

Vulnerability Assessment Summary
Opera: Two remote code execution vulnerabilities

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200701-08
(Opera: Two remote code execution vulnerabilities)

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

A possible hacker could potentially exploit the vulnerabilities to execute
arbitrary code with the rights 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.
