Use-after-free vulnerability in Adobe Flash Player before 18.0.0.375 and 19.x through 23.x before 23.0.0.162 on Windows and OS X and before 11.2.202.635 on Linux allows attackers to execute arbitrary code via unspecified vectors, a different vulnerability than CVE-2016-4272, CVE-2016-4279, CVE-2016-6923, CVE-2016-6925, CVE-2016-6926, CVE-2016-6927, CVE-2016-6929, CVE-2016-6930, CVE-2016-6931, and CVE-2016-6932.

The remote host is affected by the vulnerability described in GLSA-201610-10 (Adobe Flash Player: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Adobe Flash Player.
      Please review the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could possibly execute arbitrary code with the       privileges of the process, cause a Denial of Service condition, obtain       sensitive information, or bypass security restrictions.
  Workaround :

    There is no known workaround at this time.

Versions of Adobe Flash Player prior to 11.2.202.635, 18.0.0.375, or 23.0.0.162 are affected by the following vulnerabilities :

 - An unspecified flaw may allow a context-dependent attacker to bypass security restrictions and gain access to potentially sensitive information. No further details have been provided.
 - A use-after-free error may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code.
 - A flaw is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
 - A flaw is triggered as certain input is not properly validated when handling AVC decoding. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
 - A flaw is triggered as certain input is not properly validated when handling SWF data. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
 - A use-after-free condition is triggered when handling 'TextFormat' objects. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code.
 - An integer overflow condition is triggered as certain input is not properly validated. This may allow a context-dependent attacker to potentially execute arbitrary code.
 - A flaw is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.

This update for flash-player fixes the following security issues (APSB16-29, boo#998589) :

  - integer overflow vulnerability that could lead to code     execution (CVE-2016-4287). 

  - use-after-free vulnerabilities that could lead to code     execution (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)

  - security bypass vulnerabilities that could lead to     information disclosure (CVE-2016-4271, CVE-2016-4277,     CVE-2016-4278)

  - memory corruption vulnerabilities that could lead to     code execution (CVE-2016-4182, CVE-2016-4237,     CVE-2016-4238, CVE-2016-4274, CVE-2016-4275,     CVE-2016-4276, CVE-2016-4280, CVE-2016-4281,     CVE-2016-4282, CVE-2016-4283, CVE-2016-4284,     CVE-2016-4285, CVE-2016-6922, CVE-2016-6924)

The package description was update to reflex that the stand-alone Flash is no longer provided on x86_64 architectures (boo#977664).

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 11.2.202.635.

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.
