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.
