Microsoft on November 2-4th hosted its 11th BlueHat conference, featuring presentations from hand-picked security researchers about current and emerging security threats. Here's a short video showing what attendees had to say about this year's event:
Also, in November 2011 'Patch Tuesday', Microsoft released four security updates, to increase protection by addressing four privately reported CVEs in Microsoft Windows.
"MS11-083 (TCP/IP): This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow Remote Code Execution if an attacker sends a continuous flow of specifically crafted UDP packets to a closed port on a target system."
"The vulnerability presents itself in the specific scenario where an attacker can send a large number of specially crafted UDP packets to a random port that does not have a service listening. While processing these network packets it is observed that some used structures are referenced but not dereferenced properly. This unbalanced reference counting could eventually lead to an integer overflow of the reference counter."
