version Flash 18.0.0.203↗

• → Exploit pattern uses a crafted AS2 object with a custom valueOf function on the 'length' property assigned to TextField.filters to trigger the UAF write primitive — detect SWF files containing TextField.filters assignment with non-Array objects whose length property has a valueOf override ↗
• → PoC SWF uses large heap spray arrays filled with 0x41424344 dwords combined with TextFormat.tabStops manipulation — detect heap spray patterns of repeated 0x41424344 values in Flash heap allocations ↗

• · CVE-2015-5563 is listed as a distinct use-after-free from CVE-2015-5564; the Exploit-DB entry (37884) documents the SurfaceFilterList UAF and references the bypass of the fix for Issue 480496 in Flash 18.0.0.203 — confirm which CVE number the PoC precisely maps to before operationalizing ↗
• · The NVD source provided is for CVE-2015-5564, not CVE-2015-5563; operational details extracted from Exploit-DB 37884 may correspond to a related but distinct CVE in the same Flash UAF family ↗
