This scan was just run after installing Windows 2003 SP2 onto a fresh install of Windows 2003 R2 (SP1) with all available critical/security udpates. Unfortunately, I didn't scan this box before applying SP2. I just installed this server today and just wanted a couple of baseline security checks.
It was possible to crash the remote host by sending a specially
malformed TCP/IP packet with invalid TCP options. Only the version
2.6 of the Linux Kernel is known to be affected by this problem.
An attacker may use this flaw to disable this host remotely.
