Opera: Two remote code execution vulnerabilities


1.  Gentoo Linux Security Advisory

Version Information

Advisory Reference GLSA 200701-08 / opera
Release Date January 12, 2007
Latest Revision January 12, 2007: 01
Impact normal
Exploitable remote
Package Vulnerable versions Unaffected versions Architecture(s)
www-client/opera < 9.10 >= 9.10 All supported architectures

Related bugreports: #160369


Two vulnerabilities may allow the execution of arbitrary code.

2.  Impact Information


Opera is a multi-platform web browser.


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.


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.

3.  Resolution Information


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:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=www-client/opera-9.10"
