Adobe Flash Player versions 24.0.0.186 and earlier have an exploitable memory corruption vulnerability due to a concurrency error when manipulating a display list. Successful exploitation could lead to arbitrary code execution.

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.

Versions of Adobe Flash Player prior to 24.0.0.194 are unpatched, and therefore affected by the following vulnerabilities :

 - An unspecified flaw exists that may allow a context-dependent attacker to bypass security restrictions and gain access to potentially sensitive information.
 - An unspecified use-after-free error exists that may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code.
 - An unspecified 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.
 - A flaw exists that is triggered as certain unspecified input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
 - A flaw exists that is triggered as input is not properly validated when handling ActionRecord structures within SWF files. This may allow a context-dependent attacker to trigger an unspecified out-of-bounds condition and potentially execute arbitrary code.

This update to Adobe Flash 24.0.0.194 fixes the following vulnerabilities advised under APSB17-02 :

  - security bypass vulnerability that could lead to     information disclosure (CVE-2017-2938)

  - use-after-free vulnerabilities that could lead to code     execution (CVE-2017-2932, CVE-2017-2936, CVE-2017-2937)

  - heap buffer overflow vulnerabilities that could lead to     code execution (CVE-2017-2927, CVE-2017-2933,     CVE-2017-2934, CVE-2017-2935)

  - memory corruption vulnerabilities that could lead to     code execution (CVE-2017-2925, CVE-2017-2926,     CVE-2017-2928, CVE-2017-2930, CVE-2017-2931)

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 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 24.0.0.194.

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.
