Recommended fix High confidence

Flash Player: 18.0.0.261 (18.x) or 19.0.0.245 (19.x) or 11.2.202.548 (Linux); Adobe AIR/AIR SDK/AIR SDK & Compiler: 19.0.0.241

  1. Identify the currently installed Adobe Flash Player, Adobe AIR, Adobe AIR SDK, or Adobe AIR SDK & Compiler version on the system
  2. Navigate to the Adobe Security Bulletin APSB15-28 (https://helpx.adobe.com/security/products/flash-player/apsb15-28.html) to obtain the official fixed versions
  3. Download the appropriate fixed version based on your operating system and product type: Flash Player 18.x users should upgrade to 18.0.0.261, Flash Player 19.x users should upgrade to 19.0.0.245, Linux Flash Player users should upgrade to 11.2.202.548, Adobe AIR users should upgrade to 19.0.0.241, Adobe AIR SDK users should upgrade to 19.0.0.241, Adobe AIR SDK & Compiler users should upgrade to 19
  4. Close all web browsers and applications that may be using Flash Player or AIR
  5. Install the updated version following Adobe's standard installation procedures
  6. Verify the installed version matches the target fixed version
  7. Restart any affected applications or browsers
Caveat Flash Player and AIR are deprecated technologies; consider migrating to HTML5 as Adobe end-of-life dates approach
