Adobe Flash Player versions 23.0.0.205 and earlier, 11.2.202.643 and earlier have an exploitable use-after-free vulnerability. Successful exploitation could lead to arbitrary code execution.

Versions of Adobe Flash Player prior to 11.2.202.644 and 23.0.0.207 are unpatched, and therefore affected by the following vulnerabilities :

 - A use-after-free error exists when using ActionScript to manipulate the 'AVSegmentedSource' class allowing a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code. (CVE-2016-7857)
 - A use-after-free error exists that may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code. The issue exists in the 'addCallback' method of the 'ExternalInterface'. (CVE-2016-7858)
 - A use-after-free error exists that is triggered when handling the 'AS2 extends' operator. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code. (CVE-2016-7859)
 - A use-after-free error exists that is triggered when handling AdvertisingMetadata, Metadata, MovieClip, and TextField objects. These may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code. (CVE-2016-7860, CVE-2016-7861, CVE-2016-7862, CVE-2016-7863)
 - A use-after-free error exists when handling the Selection 'setFovus' method that may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code. (CVE-2016-7864, CVE-2016-7865)

The remote Windows host is missing KB3202790. It is, therefore, affected by multiple vulnerabilities :

  - Multiple use-after-free errors exist that allow an     unauthenticated, remote attacker to execute arbitrary     code by convincing a user to visit a website containing     specially crafted Flash content. (CVE-2016-7857,     CVE-2016-7858, CVE-2016-7859, CVE-2016-7862,     CVE-2016-7863, CVE-2016-7864)
