NetBios Fragmentation
On October 2004, a presentation was held mentioning the fragmentation weaknesses of snort. I would like to know the status of these issues.

"SNORT 2.2.0
Fails test for small TCP sends during SPDETECT
Fails test for small SMB writes during LSASS
Fails test for small DCE fragments
Score: 0/3
False positives on any IPC$ access.
More to come!"
