The remaining flaws in Acrobat and Reader products have been rated as moderate severity memory leaks and important-severity information disclosure vulnerabilities.

The flaws were reported to Adobe by independent experts and researchers from Qihoo 360, Tencent, Renmin University of China, Cisco Talos, the Chinese Academy of Sciences, Baidu, and McAfee.

Adobe addressed a new critical arbitrary code execution flaw in Flash Player, successfull exploitation could lead to arbitrary code execution in the context of the current user.
