Snort Inline模式碎片重组拒绝服务漏洞

Snort是广泛部署的开放源码网络入侵检测系统（IDS）。很多其他IDS产品中也使用了Snort及其组件。 Snort Inline在处理畸形的碎片报文时存在漏洞，远程攻击者可能利用此漏洞导致Snort崩溃。 如果在Linux平台上以Inline模式运行Snort的话，且启用了Frag3同时禁用了ipconntrack，则如果向Snort发送了特制的碎片报文的话就会导致拒绝服务。 Snort Project Snort 2.7.0 beta 1 Snort Project Snort 2.6.1.2 Snort Project Snort 2.6.1.1...

Using timing attacks to bypass intrusion detection

It's possible to use difference in timing, for example packet reasembly timeouts, of target system and IDS to bypass detection. As workaround, timing parameters of IDS should be configured to match timing parameters of protected system...
