Adobe Flash Player <= 18.0.0.203 Multiple RCE Vulnerabilities (APSB15-18) (Mac OS X)

critical Nessus Plugin ID 84732

Synopsis

The remote Mac OS X 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 Mac OS X 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.
