  • Vulnerable versions are Adobe Flash Player 22.0.0.192 and earlier (Windows/OSX) and before 11.2.202.632 on Linux; flag any Flash Player process running these versions.
  • The exploit is delivered via web-page visit or file open; monitor web traffic and email attachments for SWF files triggering SceneAndFrameData memory corruption (stack corruption).
  • ·CVE-2016-4177 is a distinct stack memory corruption vulnerability from CVE-2016-4176, though both affect the same Flash Player version ranges and were patched together in APSB16-25; ensure detections differentiate between the two CVEs.
  • ·The fixed version thresholds differ by platform: 22.0.0.209 for Windows/OSX and 11.2.202.632 for Linux; version-based detections must account for both thresholds.
