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.

NVD · unedited
Adobe Flash Player before 11.7.700.242 and 11.8.x before 11.8.800.168 on Windows and Mac OS X, before 11.2.202.310 on Linux, before 11.1.111.73 on Android 2.x and 3.x, and before 11.1.115.81 on Android 4.x; Adobe AIR before 3.8.0.1430; and Adobe AIR SDK & Compiler before 3.8.0.1430 allow attackers to execute arbitrary code or cause a denial of service (memory corruption) via unspecified vectors, a different vulnerability than CVE-2013-3361, CVE-2013-3362, and CVE-2013-5324.

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 to 11.7.700.242/11.8.800.168 (Windows/Mac), 11.2.202.310 (Linux), or 11.1.111.73/11.1.115.81 (Android); AIR to 3.8.0.1430

  1. 1. Identify the currently installed Adobe Flash Player version by navigating to 'About Flash Player' in the right-click context menu or visiting adobe.com/software/flash/about
  2. 2. Determine the correct fixed version for your platform: 11.7.700.242 or 11.8.800.168 for Windows/Mac, 11.2.202.310 for Linux, 11.1.111.73 for Android 2.x/3.x, or 11.1.115.81 for Android 4.x
  3. 3. Download the appropriate Adobe Flash Player update from the official Adobe security bulletin (apsb13-21) or getflash.adobe.com
  4. 4. Close all browsers and applications using Flash Player before installation
  5. 5. Run the installer and follow the prompts to apply the security update
  6. 6. For Adobe AIR installations, upgrade to version 3.8.0.1430 or later
  7. 7. For AIR SDK/Compiler users, update to version 3.8.0.1430 or later from the Adobe AIR download page
  8. 8. Verify the update was successful by checking the Flash Player version again
Caveat Adobe Flash Player and AIR are end-of-life products; consider migrating away from Flash-based content as Adobe ended support in December 2020
