→The exploit involves a specially crafted MP4 file (transpose.mp4) triggering an out-of-bounds read in Adobe Flash Player's AVC (H.264) processing code. Monitor for Flash Player loading external MP4 files via SWF query parameters. ↗
→The vulnerability reproduces on Chrome and Firefox for Linux when Flash Player processes the malicious MP4. Detection should cover both browser contexts on Linux platforms. ↗
→Exploitation requires serving both a SWF loader file and a crafted MP4 file from a web server. Look for SWF files accepting external file parameters (e.g., ?file=) that load MP4 content. ↗

·Affected versions are Adobe Flash Player 30.0.0.134 and earlier. Ensure detection rules scope to these versions. ↗
