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. 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)
