  • Exploit triggers a use-after-free via LoadVars.decode() when a 'watch' callback deletes the watched object mid-decode; look for ActionScript patterns combining LoadVars.decode, Object.watch, and removeTextField on the same object.
  • Flag Adobe Flash Player versions below 18.0.0.329 (Windows/OS X), below 20.0.0.306 (Windows/OS X, 19.x/20.x), or below 11.2.202.569 (Linux) as vulnerable to this UAF.
  • ·The vulnerability is triggered via unspecified vectors beyond the PoC; the LoadVars.decode/watch/removeTextField chain is one known reproduction path but may not be the only exploitation vector.
  • ·The PoC was confirmed on 64-bit Ubuntu/Chrome; behaviour on Windows/OS X may differ slightly in reproduction steps.
  • ·Adobe AIR (SDK, SDK & Compiler) before 20.0.0.260 is also affected; detections should cover AIR runtimes in addition to Flash Player.
