Opera before 10.01 does not properly restrict HTML in a (1) RSS or (2) Atom feed, which allows remote attackers to conduct cross-site scripting (XSS) attacks, and conduct cross-zone scripting attacks involving the Feed Subscription Page to read feeds or create feed subscriptions, via a crafted feed, related to the rendering of the application/rss+xml content type as "scripted content."

Version upgrade of Opera to 10.1 to fix :

  - CVE-2009-3265: CVSS v2 Base Score: 4.3 CVE-2009-3266:
    CVSS v2 Base Score: 4.3 two XSS attacks via RSS/Atom

  - CVE-2009-3831: CVSS v2 Base Score: 9.3 possible remote     arbitrary code execution via crafted domain names

The version of Opera installed on the remote host is earlier than 10.01.  Such versions are potentially affected by multiple vulnerabilities : 

  - Specially crafted domain names can cause a memory corruption in Opera, which may lead to a crash or possibly remote code execution. (938)

  - Opera may allow scripts to run on the feed subscription page, thereby gaining access to the feeds object. (939)

  - In some cases, a Web font intended to be used for page content could be incorrectly used by Opera to render parts of the user interface, including the address field. (940)
