  • CVE-2016-1001 was incorporated into the Angler Exploit Kit; monitor for Angler EK traffic patterns targeting Adobe Flash.
  • The vulnerability is triggered via a heap overflow in the Zlib codec when processing malicious FLV files in Adobe Flash; inspect FLV file delivery for exploitation attempts.
  • The PoC uses a specifically crafted file named 'smalloverflow.flv'; presence of this filename in web server logs or network traffic may indicate exploitation attempts.
  • ·The vulnerability affects Adobe Flash Player before 18.0.0.333 and 19.x–21.x before 21.0.0.182 on Windows/OS X, and before 11.2.202.577 on Linux; also Adobe AIR and AIR SDK/Compiler before 21.0.0.176. Detection should account for all affected platforms and version ranges.
  • ·The root cause vectors are officially described as 'unspecified,' limiting the ability to craft precise signature-based detections from vendor advisories alone.
