  • Detect ActionScript triggering use-after-free via TextField.gridFitType setter assigned a non-string object with toString/valueOf callbacks that call removeTextField() — look for SWF files using createTextField followed by gridFitType assignment with an object literal containing toString/valueOf function references
  • Detect SWF payloads that call removeTextField() inside a toString/valueOf callback triggered during a TextField property setter (gridFitType, thickness, tabIndex), followed by large BitmapData heap spray allocations — indicative of heap grooming after UAF
  • Other TextField setters (thickness, tabIndex) are also affected by the same UAF condition; monitor for similar patterns on those property assignments in SWF analysis
  • ·CVE-2015-5557 is one of multiple distinct use-after-free vulnerabilities in Adobe Flash Player fixed in the same bulletin; the NVD source document references CVE-2015-5564, not CVE-2015-5557 directly — confirm correct CVE mapping before deploying detections
  • ·Affected versions: Adobe Flash Player before 18.0.0.232 (Windows/OS X) and before 11.2.202.508 (Linux); Adobe AIR / AIR SDK / AIR SDK & Compiler before 18.0.0.199
