Micah Snyder reports:
A Denial-of-Service (DoS) vulnerability may occur when scanning a specially crafted email
file as a result of excessively long scan times. The issue is resolved by implementing
several maximums in parsing MIME messages and by optimizing use of memory allocation.
With Rapid7 live dashboards, I have a clear view of all the assets on my network, which ones can be exploited, and what I need to do in order to reduce the risk in my environment in real-time. No other tool gives us that kind of value and insight.
