Use-after-free vulnerability in Adobe Flash Player before 18.0.0.261 and 19.x before 19.0.0.245 on Windows and OS X and before 11.2.202.548 on Linux, Adobe AIR before 19.0.0.241, Adobe AIR SDK before 19.0.0.241, and Adobe AIR SDK & Compiler before 19.0.0.241 allows attackers to execute arbitrary code via unspecified vectors, a different vulnerability than CVE-2015-7651, CVE-2015-7652, CVE-2015-7653, CVE-2015-7654, CVE-2015-7655, CVE-2015-7656, CVE-2015-7657, CVE-2015-7658, CVE-2015-7660, CVE-2015-7661, CVE-2015-7663, CVE-2015-8042, CVE-2015-8044, and CVE-2015-8046.

• → Trigger method is MovieClip.beginGradientFill called with a malicious object (toString override) as the spreadMethod parameter — monitor SWF files invoking beginGradientFill with non-string spreadMethod arguments ↗
• → Look for SWF content that passes an object with a custom toString function as the spreadMethod argument to beginGradientFill, a classic UAF trigger pattern ↗
• → Affected versions: Adobe Flash Player before 18.0.0.261 (Windows/OS X), before 19.0.0.245 (Windows/OS X), before 11.2.202.548 (Linux); Adobe AIR / AIR SDK / AIR SDK & Compiler before 19.0.0.241 — flag processes running these versions ↗

• · The vulnerability vectors are described as 'unspecified' in the NVD entry; the exploit-db PoC links this CVE to the GradientFill UAF class but Adobe's advisory covers multiple UAF CVEs sharing the same fix batch — attribution of this specific PoC to CVE-2015-8043 exclusively should be treated with caution ↗
• · The researcher notes that many parameters beyond spreadMethod can also trigger the UAF, so detection rules scoped only to spreadMethod may miss variant exploitation paths ↗
