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-2015-7648.

• → Look for SWF files where IExternalizable.readExternal is overridden with a non-function value — this is the trigger condition for the type confusion leading to memory corruption. ↗
• → Inspect SWF files (especially decompressed via flasm -x) for the string 'readExternal' in bytecode — PoC required manual patching of 'teadExternal' to 'readExternal' to trigger the vulnerability. ↗
• → Flag Adobe Flash Player versions below 18.0.0.255, 19.x below 19.0.0.226 (Windows/OS X), and below 11.2.202.540 (Linux) as vulnerable to this type confusion code execution. ↗

• · The PoC SWF does not compile directly from the provided ActionScript source — the working exploit requires decompressing the SWF with flasm and manually patching the bytecode string. ↗
• · CVE-2015-7647 is a distinct type confusion vulnerability from CVE-2015-7648, though both are fixed in the same Adobe bulletin APSB15-27 and share the same vulnerable version ranges. ↗
