Opera before 11.10 allows remote attackers to hijack (1) searches and (2) customizations via unspecified third party applications.

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.

The remote host is running the Opera web browser. 

Versions of Opera earlier than 11.10 are potentially affected by multiple vulnerabilities :   - An unspecified vulnerability allows remote attackers to hijack searches and customizations using unspecified third-party applications. (CVE-2011-2634)

  - Several errors exist that can cause application crashes.  Affected items or functionalities are the handling of the CSS pseudo-class ': hover' if used with transforms on a floated element, unspecified web content, and the handling of an embedded Java applet with empty parameters. (CVE-2011-2635, CVE-2011-2636, CVE-2011-2637, CVE-2011-2638, CVE-2011-2640)

  - An error in the handling of hidden animated GIF images can cause a denial of service through CPU consumption as image repaints are triggered. (CVE-2011-2639)

The version of Opera installed on the remote Windows host is earlier than 11.10 and thus is potentially affected by the following vulnerabilities :

  - An unspecified vulnerability allows remote attackers     to hijack searches and customizations using unspecified     third-party applications. (CVE-2011-2634)

  - Several errors exist that can cause application     crashes.
