Vulnerability Assessment Details
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.
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
"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"
