Hi there, Just want to let you know, the Fortinet's FortiGuard Global Security Research Team has provided an in-depth research on the recent PDF zero-day exploit (CVE-2009-3459). http://www.fortiguard.com/analysis/pdfanalysis.html "Taking a look back over this 0-day attack as a whole, each single part of it is somehow ingenious - whether it be the vulnerability, operational exploitation, the logic behind it, the way to leverage it or the final shellcode. The exploitation method through the heap overflow, which may also be used in future Adobe Reader exploits, is particularly innovative in itself."
