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

  - An unspecified use-after-free error exists due to 
    improper validation of user-supplied input. A remote
    attacker can exploit this, via a specially crafted web
    page, to dereference already freed memory, resulting in
    a crash of the browser. (CVE-2011-4152)

  - An error exists related to the handling of certain font 
    manipulations inside dynamically added or specifically
    embedded SVG images or SVG content in nested frames. A
    remote attacker can exploit this to crash the
    application or execute arbitrary code.
    (BID 50044 / Issue #1002)

  - Multiple unspecified errors exist that allow an attacker
    to cause a stack overflow condition, resulting in a
    browser crash.");
