Subject: A new datapoint for 0day lifetime
|
Justine Aitel made the following statements during a July 2007 presentation:
*"Real-world 0day Statistics*
*Average 0day lifetime: 348 days
Shortest life: 99 days
Longest life: 1080 (3 years)"
*- http://immunityinc.com/downloads/0day_IPO.pdf*
*I'd like to include a new datapoint for those averages.
uTorrent and Bittorrent Mainline have included an unpatched Unicode stack
overflow in its code-base for at least 2 years. It was finally patched on
the 5th August 2008 with 1.8 Release Candidate 7.
Full details and discussion in the attached paper.
