Synopsis

The remote Windows host has a browser plugin installed that is affected by multiple remote code execution vulnerabilities.

Description

The version of Adobe Flash Player installed on the remote Windows host is equal or prior to version 18.0.0.203. It is, therefore, affected by multiple remote code execution vulnerabilities :

- A use-after-free error exists in the opaqueBackground class in the ActionScript 3 (AS3) implementation. A remote attacker, via specially crafted Flash content, can dereference already freed memory, resulting in the execution of arbitrary code. (CVE-2015-5122)

- A use-after-free error exists in the BitmapData class in the ActionScript 3 (AS3) implementation. A remote attacker, via specially crafted Flash content, can dereference already freed memory, resulting in the execution of arbitrary code. (CVE-2015-5123)

Solution

Upgrade to Adobe Flash Player version 18.0.0.209 or later.

Alternatively, Adobe has made version 13.0.0.309 available for those installations that cannot be upgraded to 18.x.
