Opera before 11.60 does not properly handle certificate revocation, which has unspecified impact and remote attack vectors related to "corner cases."

opera was updated to version 11.60 to fix several security issues

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)
