• → Use-after-free triggered via ActionScript TextField.antiAliasType setter when assigned an object whose toString() method removes the parent MovieClip (and thus frees the TextField) before the property write completes. ↗
• → Look for SWF files that assign a non-string object (with a custom toString method) to TextField.antiAliasType — this is the specific ActionScript pattern that triggers the vulnerability. ↗
• → The exploit pattern involves calling removeMovieClip() inside a toString callback triggered during a property setter, causing the underlying object to be freed mid-operation. Monitor Flash content invoking removeMovieClip within toString overrides. ↗

• · The vulnerability affects 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; also Adobe AIR before 19.0.0.241 and its SDK variants. The CVE referenced in the NVD source (CVE-2015-8043) is a related but distinct use-after-free; CVE-2015-8046 is listed as one of the differentiated vulnerabilities. ↗
