  • Look for ActionScript 2 usage of addProperty on flash.geom namespace to override the ColorTransform constructor with a getter — this is the trigger mechanism for the info leak.
  • Detect SWF files that call Transform.colorTransform getter after overwriting the ColorTransform constructor via addProperty, combined with MovieClip removal inside the getter callback (removeMovieClip), indicating UAF/info-leak exploitation pattern.
  • Flag Adobe Flash Player versions below 18.0.0.366 (Windows/OS X), below 22.0.0.209 in the 19.x–22.x range (Windows/OS X), or below 11.2.202.632 (Linux) as vulnerable to this information disclosure.
  • ·The PoC prints unallocated memory values (greenMultiplier, blueMultiplier, color) to the screen rather than exfiltrating them over the network, so there may be no network-based IOC to detect for basic exploitation.
  • ·The vulnerability trigger relies on ActionScript 2 (AS2) features (addProperty, createEmptyMovieClip), so detection should focus on AS2-based SWF content specifically.
