Use-after-free vulnerability in the DisplayObject class in the ActionScript 3 (AS3) implementation in Adobe Flash Player 13.x through 13.0.0.302 on Windows and OS X, 14.x through 18.0.0.203 on Windows and OS X, 11.x through 11.2.202.481 on Linux, and 12.x through 18.0.0.204 on Linux Chrome installations allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via crafted Flash content that leverages improper handling of the opaqueBackground property, as exploited in the wild in July 2015.

The version of Google Chrome OS on the remote mobile host is prior to 43.0.2357.132 and thus unpatched for the following vulnerabilities :

 - A use-after-free error exists in the opaqueBackground class in the ActionScript 3 (AS3) implementation. A remote attacker, via specially crafted Flash content, can dereference already freed memory, resulting in the execution of arbitrary code. (CVE-2015-5122) 
 - A use-after-free error exists in the BitmapData class in the ActionScript 3 (AS3) implementation. A remote attacker, via specially crafted Flash content, can dereference already freed memory, resulting in the execution of arbitrary code. (CVE-2015-5123) 
 - A flaw exists due to user-supplied input not being properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code. (CVE-2015-5124) 
 - An information disclosure vulnerability exists that allows an attacker to guess the address for the Flash heap. (CVE-2015-3097) 
 - Multiple heap-based buffer overflow vulnerabilities exist that allow arbitrary code execution. (CVE-2015-3135, CVE-2015-4432, CVE-2015-5118) 
 - Multiple memory corruption vulnerabilities exist that allow arbitrary code execution. (CVE-2015-3117, CVE-2015-3123, CVE-2015-3130, CVE-2015-3133, CVE-2015-3134, CVE-2015-4431) 
 - Multiple NULL pointer dereference flaws exist. (CVE-2015-3126, CVE-2015-4429) 
 - A security bypass vulnerability exists that results in an information disclosure. (CVE-2015-3114) 
 - Multiple type confusion vulnerabilities exist that allow arbitrary code execution. (CVE-2015-3119, CVE-2015-3120, CVE-2015-3121, CVE-2015-3122, CVE-2015-4433) 
 - Multiple use-after-free errors exist that allow arbitrary code execution. (CVE-2015-3118, CVE-2015-3124, CVE-2015-5117, CVE-2015-3127, CVE-2015-3128, CVE-2015-3129, CVE-2015-3131, CVE-2015-3132, CVE-2015-3136, CVE-2015-3137, CVE-2015-4428, CVE-2015-4430, CVE-2015-5119) 
 - Multiple same-origin policy bypass vulnerabilities exist that allow information disclosure. (CVE-2014-0578, CVE-2015-3115, CVE-2015-3116, CVE-2015-3125, CVE-2015-5116) 
 - A memory corruption issue exists due to improper validation of user-supplied input. An attacker can exploit this to execute arbitrary code. (CVE-2015-5124)

The version of Google Chrome on the remote host is prior to 43.0.2357.134 and is affected by the following vulnerabilities in the Adobe Flash player component :

 - A use-after-free error exists in the opaqueBackground class in the ActionScript 3 (AS3) implementation. A remote attacker, via specially crafted Flash content, can dereference already freed memory, resulting in the execution of arbitrary code. (CVE-2015-5122) 
 - A use-after-free error exists in the BitmapData class in the ActionScript 3 (AS3) implementation. A remote attacker, via specially crafted Flash content, can dereference already freed memory, resulting in the execution of arbitrary code. (CVE-2015-5123)

The remote host is affected by the vulnerability described in GLSA-201508-01 (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 18.0.0.209 are outdated and thus unpatched for the following vulnerabilities :

  - A use-after-free error exists in the opaqueBackground class in the ActionScript 3 (AS3) implementation. A remote attacker, via specially crafted Flash content, can dereference already freed memory, resulting in the execution of arbitrary code. (CVE-2015-5122)
  - A use-after-free error exists in the BitmapData class in the ActionScript 3 (AS3) implementation. A remote attacker, via specially crafted Flash content, can dereference already freed memory, resulting in the execution of arbitrary code. (CVE-2015-5123)

flash-player was updated to fix two security issues.

These security issues were fixed :

  - CVE-2015-5123: Use-after-free vulnerability in the     BitmapData class in the ActionScript 3 (AS3)     implementation in Adobe Flash Player allowed remote     attackers to execute arbitrary code or cause a denial of     service (memory corruption) via crafted Flash content     that overrides a valueOf function (bsc#937752).

  - CVE-2015-5122: Use-after-free vulnerability in the     DisplayObject class in the ActionScript 3 (AS3)     implementation in Adobe Flash Player allowed remote     attackers to execute arbitrary code or cause a denial of     service (memory corruption) via crafted Flash content     that leverages improper handling of the opaqueBackground     property (bsc#937752).

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.

Adobe Flash Player was updated to 11.2.202.491 to fix two security issues.

The following vulnerabilities were fixed :

  - CVE-2015-5122: Specially crafted Flash content allowed     attackers to execute arbitrary code via a use-after-free     vulnerability in the DisplayObject class in the     ActionScript 3 (AS3) implementation.

  - CVE-2015-5123: Specially crafted Flash content allowed     attackers to execute arbitrary code via a use-after-free     vulnerability in the BitmapData class in the     ActionScript 3 (AS3) implementation.

An updated Adobe Flash Player package that fixes two security issues is now available for Red Hat Enterprise Linux 5 and 6 Supplementary.

Red Hat Product Security has rated this update as having Critical security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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

This update fixes two vulnerabilities in Adobe Flash Player. These vulnerabilities are detailed in the Adobe Security Bulletin APSB15-18 listed in the References section.

Two flaws were found in the way flash-plugin displayed certain SWF content. An attacker could use these flaws to create a specially crafted SWF file that would cause flash-plugin to crash or, potentially, execute arbitrary code when the victim loaded a page containing the malicious SWF content. (CVE-2015-5122, CVE-2015-5123)

All users of Adobe Flash Player should install this updated package, which upgrades Flash Player to version 11.2.202.491.
