Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

Adobe Flash Player before 10.3.183.90 and 11.x before 11.7.700.224 on Windows, before 10.3.183.90 and 11.x before 11.7.700.225 on Mac OS X, before 10.3.183.90 and 11.x before 11.2.202.291 on Linux, before 11.1.111.59 on Android 2.x and 3.x, and before 11.1.115.63 on Android 4.x; Adobe AIR before 3.7.0.2090 on Windows and Android and before 3.7.0.2100 on Mac OS X; and Adobe AIR SDK & Compiler before 3.7.0.2090 on Windows and before 3.7.0.2100 on Mac OS X allow attackers to execute arbitrary code or cause a denial of service (memory corruption) via unspecified vectors.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis
How this class of weakness works · CWE-119

The program reads or writes outside the bounds of an allocated buffer, corrupting adjacent memory. With crafted input an attacker can overwrite control data and, with effort, redirect execution to their own code. Remediation ranges from bounds checking and safe library functions to compiler mitigations, usually alongside a careful audit of the surrounding code.

Recommended fix High confidence

Flash Player 10.3.183.90 / 11.7.700.224-225 / 11.2.202.291 / 11.1.111.59 / 11.1.115.63 (platform-dependent); Adobe AIR 3.7.0.2090/3.7.0.2100 (platform-dependent); Adobe AIR SDK 3.7.0.2090/3.7.0.2100 (platform-dependent)

  1. 1. Identify the installed Adobe Flash Player version by navigating to 'About Flash Player' in the player or checking the system's installed programs
  2. 2. Identify the Adobe AIR version by checking the system's installed programs or the AIR version in the system tray
  3. 3. Download the appropriate fixed version from the Adobe Security Bulletin APSB13-16: http://www.adobe.com/support/security/bulletins/apsb13-16.html
  4. 4. For Flash Player: Upgrade to version 10.3.183.90, 11.7.700.224/225, 11.2.202.291, 11.1.111.59, or 11.1.115.63 depending on your platform (Windows/Mac/Linux/Android)
  5. 5. For Adobe AIR: Upgrade to version 3.7.0.2090 (Windows/Android) or 3.7.0.2100 (Mac OS X)
  6. 6. For AIR SDK/Compiler: Upgrade to version 3.7.0.2090 (Windows) or 3.7.0.2100 (Mac OS X)
  7. 7. Restart any browsers and applications using Flash Player or AIR after the upgrade
  8. 8. Verify the new version is installed correctly
Caveat Minor: Upgrading patch versions within the same major release typically has minimal risk; however, as Flash Player is end-of-life, consider migrating away from Flash-based content
