  • Look for ActionScript use of `addProperty` on `flash.geom` namespace to replace the `Transform` constructor with a getter — this is the trigger mechanism for the use-after-free.
  • Detect calls to `ASnative(900, 419)` within ActionScript, which is used to invoke the vulnerable MovieClip Transform getter path.
  • Suspicious SWF files that call `createEmptyMovieClip` followed by `addProperty` on `flash.geom` and then `removeMovieClip` inside the property getter should be flagged as potential CVE-2016-4230 exploitation attempts.
  • ·The vulnerability affects Adobe Flash Player before 18.0.0.366 (Windows/OS X), versions 19.x–22.x before 22.0.0.209 (Windows/OS X), and before 11.2.202.632 on Linux; exploitation is only possible on these unpatched versions.
  • ·The NVD source document is for CVE-2016-4229, which lists CVE-2016-4230 as a related but distinct use-after-free variant in the same Flash Player versions; the PoC on Exploit-DB is attributed to CVE-2016-4230 (MovieClip Transform getter UAF).
