FreeBSD : snort -- Back Orifice preprocessor buffer overflow vulnerability (97d45e95-3ffc-11da-a263-0001020eed82)
Jennifer Steffens reports : The Back Orifice preprocessor contains a stack-based buffer overflow. This vulnerability could be leveraged by an attacker to execute code remotely on a Snort sensor where the Back Orifice preprocessor is enabled. However, there are a number of factors that make remote...

SNORT Incorrect fragmented packet reassembly
Snort 2.4.3 has a bug in processing fragmented ip packets which has ip options. frag3 preprocessor of snort skips ipoptionlength bytes from end of the ip options when reassembling packet, thus allowing anyone to evade ids. Guys at snort.org already informed and are fixing the problem...
Verified evasion in Snort
pre Dan Kaminsky gave a presentation at shmoocon and mentioned using ip fragmentation timers to evade intrusion detection systems. It's a pretty straightforward technique and easy to code up so we decided to look and see if Snort was vulnerable...
Snort Back Orifice Pre-Preprocessor Buffer Overflow
This module exploits a stack buffer overflow in the Back Orifice pre-processor module included with Snort versions 2.4.0, 2.4.1, 2.4.2, and 2.4.3. This vulnerability could be used to completely compromise a Snort sensor, and would typically gain an attacker full root or administrative privileges...
