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