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

Vulnerability Scan Summary
Opera: Two remote code execution vulnerabilities

Detailed Explanation for this Vulnerability Test
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.


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.


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


All Opera users should update to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-client/opera-9.10"

Threat Level: Medium
