  • →CVE-2015-8422 is a use-after-free in Adobe Flash Player's TextField.setFormat method. Monitor for SWF files invoking TextField.setFormat with an object whose valueOf property is overridden (i.e., a custom valueOf function), which is the trigger mechanism for the UAF. ↗
  • →Look for Flash content calling mc.removeMovieClip() inside a valueOf callback triggered during TextField.setFormat execution — this is the specific exploitation pattern that frees the parent MovieClip while it is still in use. ↗
  • →The vulnerability affects Adobe Flash Player before 18.0.0.268 and 19.x/20.x before 20.0.0.228 on Windows/OS X, and before 11.2.202.554 on Linux. Flag processes running older Flash Player versions as high-risk. ↗
  • ·The exploit PoC uses ActionScript 2 (createEmptyMovieClip, createTextField APIs), indicating the vulnerability is exercised via AS2 SWF content. Detection rules should account for AS2-based SWF files specifically. ↗
