Versions of Adobe Flash Player prior to 24.0.0.221 are unpatched, and therefore affected by the following vulnerabilities :

 - An unspecified use-after-free error exists that may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code. No further details have been provided. (CVE-2017-2982, CVE-2017-2985, CVE-2017-2993)
 - An overflow condition that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to cause a heap-based buffer overflow, potentially allowing the execution of arbitrary code. (CVE-2017-2984)
 - An overflow condition exists that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to cause a heap-based buffer overflow, potentially allowing the execution of arbitrary code. (CVE-2017-2986, CVE-2017-2992)
 - An unspecified integer overflow condition exists that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to potentially execute arbitrary code. (CVE-2017-2987)
 - A flaw exists that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code. (CVE-2017-2988, CVE-2017-2990, CVE-2017-2991, CVE-2017-2996)
 - An out-of-bounds access flaw exists that is triggered during the handling of a specially crafted 'MediaPlayer' object. This may allow a context-dependent attacker to potentially execute arbitrary code. (CVE-2017-2994)
 - A type confusion flaw exists that is triggered during the handling of specially crafted 'MessageChannel' objects. This may allow a context-dependent attacker to potentially execute arbitrary code. (CVE-2017-2995)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Adobe Flash Player versions 24.0.0.194 and earlier have an exploitable heap overflow vulnerability in the     h264 decoder routine. Successful exploitation could lead to arbitrary code execution. (CVE-2017-2984)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of Adobe Flash Player installed on the remote Windows host is equal or prior to version 24.0.0.194. It is, therefore, affected by multiple vulnerabilities :

  - Multiple use-after-free errors exist that allow an     unauthenticated, remote attacker to execute arbitrary     code. (CVE-2017-2982, CVE-2017-2985, CVE-2017-2993,     CVE-2017-2994).

  - Multiple heap buffer overflow conditions exist that     allow an unauthenticated, remote attacker to execute     arbitrary code. (CVE-2017-2984, CVE-2017-2986,     CVE-2017-2992).

  - An integer overflow condition exists that allows an     unauthenticated, remote attacker to execute arbitrary     code. (CVE-2017-2987).

  - Multiple memory corruption issues exist that allow an     unauthenticated, remote attacker to execute arbitrary     code. (CVE-2017-2988, CVE-2017-2990, CVE-2017-2991,     CVE-2017-2996).

  - A type confusion error exists that allows an     unauthenticated, remote attacker to execute arbitrary     code. (CVE-2017-2995)

The version of Adobe Flash Player installed on the remote macOS or Mac OS X host is equal or prior to version 24.0.0.194. It is, therefore, affected by multiple vulnerabilities :

  - Multiple use-after-free errors exist that allow an     unauthenticated, remote attacker to execute arbitrary     code. (CVE-2017-2982, CVE-2017-2985, CVE-2017-2993,     CVE-2017-2994).

  - Multiple heap buffer overflow conditions exist that     allow an unauthenticated, remote attacker to execute     arbitrary code. (CVE-2017-2984, CVE-2017-2986,     CVE-2017-2992).

  - An integer overflow condition exists that allows an     unauthenticated, remote attacker to execute arbitrary     code. (CVE-2017-2987).

  - Multiple memory corruption issues exist that allow an     unauthenticated, remote attacker to execute arbitrary     code. (CVE-2017-2988, CVE-2017-2990, CVE-2017-2991,     CVE-2017-2996).

  - A type confusion error exists that allows an     unauthenticated, remote attacker to execute arbitrary     code. (CVE-2017-2995)

The remote host is affected by the vulnerability described in GLSA-201702-20 (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 or bypass security restrictions.
  Workaround :

    There is no known workaround at this time.

An update for flash-plugin is now available for 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 24.0.0.221.

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.
