The version of Adobe Flash Player installed on the remote macOS or Mac OS X host is equal or prior to version 23.0.0.205. 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)

  - Multiple type confusion 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-2016-7860,     CVE-2016-7861, CVE-2016-7865)

An update for flash-plugin is now available for Red Hat Enterprise Linux 5 Supplementary and Red Hat Enterprise Linux 6 Supplementary.

Red Hat Product Security has rated this update as having a security impact of Critical. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

The flash-plugin package contains a Mozilla Firefox compatible Adobe Flash Player web browser plug-in.

This update upgrades Flash Player to version 11.2.202.644.

Security Fix(es) :

* This update fixes multiple vulnerabilities in Adobe Flash Player.
These vulnerabilities, detailed in the Adobe Security Bulletin listed in the References section, could allow an attacker to create a specially crafted SWF file that would cause flash-plugin to crash, execute arbitrary code, or disclose sensitive information when the victim loaded a page containing the malicious SWF content.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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)
