Two vulnerabilities may allow the execution of arbitrary code.
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.
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:
