Adobe Flash Player before 18.0.0.382 and 19.x through 23.x before 23.0.0.185 on Windows and OS X and before 11.2.202.637 on Linux allows attackers to execute arbitrary code by leveraging an unspecified "type confusion."

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.

Adobe reports :

Adobe has released security updates for Adobe Flash Player for Windows, Macintosh, Linux and ChromeOS. These updates address critical vulnerabilities that could potentially allow an attacker to take control of the affected system.

These updates resolve a type confusion vulnerability that could lead to code execution (CVE-2016-6992).

These updates resolve use-after-free vulnerabilities that could lead to code execution (CVE-2016-6981, CVE-2016-6987).

These updates resolve a security bypass vulnerability (CVE-2016-4286).

These updates resolve memory corruption vulnerabilities that could lead to code execution (CVE-2016-4273, CVE-2016-6982, CVE-2016-6983, CVE-2016-6984, CVE-2016-6985, CVE-2016-6986, CVE-2016-6989, CVE-2016-6990).

Versions of Adobe Flash Player prior to 11.2.202.637, 18.0.0.382, or 23.0.0.185 are unpatched, and therefore affected by the following vulnerabilities :

 - An unspecified type confusion flaw may allow a context-dependent attacker to execute arbitrary code. 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. No further details have been provided. 
 - An unspecified flaw may allow a context-dependent attacker to bypass security restrictions. No further details have been provided.
 - 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.

flash-player was updated to version 11.2.202.637 to fix the following issues (bsc#1004019) :

  - CVE-2016-6992: A type confusion vulnerability that could     lead to code execution. CVE-2016-6981, CVE-2016-6987:
    use-after-free vulnerabilities that could lead to code     execution CVE-2016-4286: Security bypass vulnerability     CVE-2016-4273, CVE-2016-6982, CVE-2016-6983,     CVE-2016-6984, CVE-2016-6985, CVE-2016-6986,     CVE-2016-6989, CVE-2016-6990: Memory corruption     vulnerabilities that could lead to code execution Also     the EULA was updated to version 23.0 (bsc#1003993).

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.

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 11.2.202.637.

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.
(CVE-2016-4273, CVE-2016-4286, CVE-2016-6981, CVE-2016-6982, CVE-2016-6983, CVE-2016-6984, CVE-2016-6985, CVE-2016-6986, CVE-2016-6987, CVE-2016-6989, CVE-2016-6990, CVE-2016-6992)

This update for flash-player fixes the following security issues :

  - CVE-2016-4286: Unspecified security bypass vulnerability

  - CVE-2016-6981: Unspecified use-after-free vulnerability     that could lead to code execution

  - CVE-2016-6982: Unspecified memory corruption     vulnerability that could lead to code execution

  - CVE-2016-6983: Unspecified memory corruption     vulnerability that could lead to code execution

  - CVE-2016-6984: Unspecified memory corruption     vulnerability that could lead to code execution

  - CVE-2016-6985: Unspecified memory corruption     vulnerability that could lead to code execution

  - CVE-2016-6986: Unspecified memory corruption     vulnerability that could lead to code execution

  - CVE-2016-6992: Unspecified type confusion vulnerability     that could lead to code execution

The EULA was updated to version 23.0 (boo#1003993).

The remote Windows host is missing KB3194343. It is, therefore, affected by multiple vulnerabilities :

  - A type confusion error exists that allows an     unauthenticated, remote attacker to execute arbitrary     code. (CVE-2016-6992)

  - Multiple use-after-free errors exist that allow an     unauthenticated, remote attacker to execute arbitrary     code. (CVE-2016-6981, CVE-2016-6987)

  - An unspecified security bypass vulnerability exists that     allows an unauthenticated, remote attacker to bypass     security restrictions. (CVE-2016-4286)

  - Multiple memory corruption issues exist that allow an     unauthenticated, remote attacker to execute arbitrary     code. (CVE-2016-4273, CVE-2016-6982, CVE-2016-6983,     CVE-2016-6984, CVE-2016-6985, CVE-2016-6986,     CVE-2016-6989, CVE-2016-6990)   Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Adobe Flash Player installed on the remote Mac OS X host is equal or prior to version 23.0.0.162. It is, therefore, affected by multiple vulnerabilities :

  - A type confusion error exists that allows an     unauthenticated, remote attacker to execute arbitrary     code. (CVE-2016-6992)

  - Multiple use-after-free errors exist that allow an     unauthenticated, remote attacker to execute arbitrary     code. (CVE-2016-6981, CVE-2016-6987)
