Opera Multiple Vulnerabilities

Multiple vulnerabilities have been identified in Opera, where some have unknown impacts and other can be exploited by malicious people to conduct cross-site scripting attacks, bypass certain security restrictions, and compromise a user's system.

1. An unspecified error when handling CORS (Cross-Origin Resource Sharing) requests can be exploited to bypass the same origin policy and e.g. disclose sensitive information from another domain.
2. An error when handling Data URIs can be exploited to conduct cross-site scripting attacks.
3. An error when handling SVG images can be exploited to execute arbitrary code.
