• → CVE-2015-5127 is a Use-After-Free triggered via the DisplacementMapFilter.mapBitmap property in Adobe Flash AS2; monitor for SWF files invoking DisplacementMapFilter with mapBitmap manipulation alongside BitmapData object operations. ↗
• → The exploit bypasses the patch by calling getPixel32 to clear an internal use-marker before triggering the UAF; look for AS2 code patterns combining getPixel32 calls with valueOf overrides and object reallocation loops (e.g., TextFormat with tabStops). ↗
• → Exploit SWF contains a manually patched byte sequence at offset 0x92B (all 0x17 / actionPOP bytes); static analysis of SWF bytecode for a run of 8 consecutive 0x17 bytes at that offset can identify the weaponized file. ↗
• → Crash dereference address 0x41424344 is a canary value indicating successful UAF exploitation; memory-crash telemetry or crash dumps referencing this address in Flash processes are a strong indicator of exploitation attempts. ↗

• · The PoC SWF (mapBitmap_v2_as2.swf) must be manually byte-patched after compilation from the FLA source; an unpatched compiled SWF will NOT trigger the vulnerability. ↗
• · The exploit targets Flash StandAlone Debug 17.0.0.188 on Win7 x64 SP1; it is a patch-bypass of a prior fix (Issue 457680) and may behave differently on other Flash versions or OS configurations. ↗
• · CVE-2015-5127 is one of 14 distinct use-after-free vulnerabilities patched in the same Adobe Flash update; detections should not conflate it with the other CVEs listed in the same bulletin. ↗
