Description

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.
