Description:   Multiple vulnerabilities were reported in Adobe Flash Player. A remote user can cause arbitrary code to be executed on the target user's system. A remote user can obtain potentially sensitive information on the target system.

A remote user can bypass security to obtain potentially sensitive information [CVE-2016-4271, CVE-2016-4277, CVE-2016-4278].

A remote user can create specially crafted content that, when loaded by the target user, will execute arbitrary code on the target user's system.

A use-after-free memory error may occur [CVE-2016-4272, CVE-2016-4279, CVE-2016-6921, CVE-2016-6923, CVE-2016-6925, CVE-2016-6926, CVE-2016-6927, CVE-2016-6929, CVE-2016-6930, CVE-2016-6931, CVE-2016-6932].
