  • Exploit triggers a heap-based buffer overflow when loading a crafted .FLV file using the Nellymoser audio codec in Adobe Flash Player; monitor for Flash Player loading .FLV files with Nellymoser audio codec, especially via SWF wrappers like LoadMP4.swf.
  • Crash manifests as a heap buffer overflow in 64-bit Flash (Chrome Linux) at a movaps instruction writing past the end of committed heap memory; look for Flash process crashes or abnormal memory access patterns at movaps instructions in the Flash plugin process.
  • The vulnerability bears similarities to CVE-2015-3043 (APT28-linked exploitation); treat detections of this CVE with elevated threat actor attribution concern.
  • ·Reproduction may require multiple page refreshes; a single load may not trigger the overflow reliably.
  • ·Exploit was demonstrated specifically against 64-bit Flash in Chrome on Linux; behavior on other platforms or architectures may differ.
