• → Look for ActionScript calls to MovieClip.lineStyle() where one or more String parameters is an object with a custom toString() method — this is the trigger pattern for the use-after-free. ↗
• → Detect SWF files invoking createEmptyMovieClip followed by lineStyle with a non-string (object) argument and removeMovieClip inside a toString callback — the specific API sequence used in the PoC. ↗
• → Flag Adobe Flash Player versions below 18.0.0.261 (Windows/OS X) or below 11.2.202.548 (Linux) and Adobe AIR below 19.0.0.241 as vulnerable to this use-after-free. ↗

• · The NVD source document is for CVE-2015-8043, not CVE-2015-8044; CVE-2015-8044 is listed only as a related sibling vulnerability sharing the same affected version ranges and use-after-free class. No dedicated CVE-2015-8044-specific technical detail is available in the provided sources. ↗
• · The Exploit-DB PoC (39021) is attributed to CVE-2015-8044 via the MovieClip.lineStyle use-after-free primitive, but the exact CVE mapping should be verified against Adobe's official bulletin (APSB15-28) as multiple sibling UAF CVEs share the same affected component. ↗
