Opera before 10.01 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted domain name.

The remote host is affected by the vulnerability described in GLSA-201206-03 (Opera: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Opera. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to open a specially crafted web       page, possibly resulting in execution of arbitrary code with the       privileges of the process or a Denial of Service condition. A remote       attacker may be able to: trick users into downloading and executing       arbitrary files, bypass intended access restrictions, spoof trusted       content, spoof URLs, bypass the Same Origin Policy, obtain sensitive       information, force subscriptions to arbitrary feeds, bypass the popup       blocker, bypass CSS filtering, conduct cross-site scripting attacks, or       have other unknown impact.
    A local attacker could perform symlink attacks to overwrite arbitrary       files with the privileges of the user running the application or possibly       obtain sensitive information.
    A physically proximate attacker may be able to access an email account.
  Workaround :

    There is no known workaround at this time.

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

Opera Team Reports :

- Fixed an issue where certain domain names could allow execution of arbitrary code, as reported by Chris Weber of Casaba Security

- Fixed an issue where scripts can run on the feed subscription page, as reported by Inferno

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)
