Synopsis

The remote host contains a web browser that is affected by multiple vulnerabilities.

Description

The version of Opera installed on the remote Windows host is prior to 11.60. It is, therefore, affected by multiple vulnerabilities :

- An unspecified error exists that can allow URL spoofing in the address bar. (CVE-2011-4010)

- Top level domain separation rules are not honored for two-letter top level domains, e.g., '.us' or '.uk', and some three-letter top level domains. This error can allow sites to set the scripting context to the top level domain. Further, this can allow sites to set and read cookies from other sites whose scripting context is set to the same top level domain. (CVE-2011-4681)

- An error exists in the implementation of the JavaScript 'in' operator that can allow sites to verify the existence of variables of sites in other domains.
(CVE-2011-4682)

- An unspecified, moderately severe issue exists. Details are to be disclosed by the vendor at a later date.
(CVE-2011-4683)

- The browser does not properly handle certain corner cases related to certificate revocation. (CVE-2011-4684)

- Unspecified content can cause the 'Dragonfly' component of the browser to crash. (CVE-2011-4685)

- An unspecified error exists related to the 'Web Workers' implementation that can allow application crashes. (CVE-2011-4686)

- An unspecified error exists that can allow remote content to cause denial of service conditions via resource consumption. (CVE-2011-4687)

- An information disclosure vulnerability, known as BEAST, exists in the SSL 3.0 and TLS 1.0 protocols due to a flaw in the way the initialization vector (IV) is selected when operating in cipher-block chaining (CBC) modes. A man-in-the-middle attacker can exploit this to obtain plaintext HTTP header data, by using a blockwise chosen-boundary attack (BCBA) on an HTTPS session, in conjunction with JavaScript code that uses the HTML5 WebSocket API, the Java URLConnection API, or the Silverlight WebClient API. (CVE-2011-3389)

Solution

Upgrade to Opera 11.60 or later.
