Adobe Flash Player before 18.0.0.255 and 19.x before 19.0.0.226 on Windows and OS X and before 11.2.202.540 on Linux allows attackers to execute arbitrary code by leveraging an unspecified "type confusion," a different vulnerability than CVE-2015-7647.

• → Detect SWF files exploiting type confusion via ObjectEncoder.dynamicPropertyWriter overridden with a non-function value — look for bytecode where 'writeDynamicProperties' is patched (e.g., string 'writeDocumentProperties' replacing 'triteDocumentProperties' in decompressed SWF). ↗
• → Flag ActionScript/SWF payloads that set flash.net.ObjectEncoding.dynamicPropertyWriter to a non-function object and then call ByteArray.writeObject() on a dynamic-property-bearing object, as this triggers the type confusion code path. ↗
• → Monitor for decompressed (flasm -x) SWF files in transit or on disk, as the PoC requires the SWF to be decompressed and manually modified at the bytecode level to bypass compiler type checks. ↗

• · The type confusion is not triggerable via normal ActionScript compilation — the SWF bytecode must be manually modified post-compilation to override writeDynamicProperties with a non-function, meaning standard static AS3 analysis will miss this variant. ↗
• · Affected versions span multiple platforms: Flash Player before 18.0.0.255 and 19.x before 19.0.0.226 on Windows/OS X, and before 11.2.202.540 on Linux — detections should account for all three platform version ranges. ↗
