Vulnerability Title
N/A
Vulnerability Description
Integer overflow in the TCP stream reassembly module (stream4) for Snort 2.0 and earlier allows remote attackers to execute arbitrary code via large sequence numbers in packets, which enable a heap-based buffer overflow.

Vulnerability Title
Snort TCP流重组预处理器远程整数溢出导致堆缓冲区溢出漏洞
Vulnerability Description
Snort是一个开放源码的流行的网络入侵检测系统。 stream4预处理模块在计算重组数据流偏移时存在一个整数溢出，远程攻击者可以利用这个漏洞对Snort进程堆缓冲区溢出攻击，可能以Snort进程权限在系统上执行任意指令。 stream4预处理模块是Snort在进行包分析前重组TCP通信的一个插件，也可以用于探测多种类型的IDS逃避攻击。这个模块在计算重组数据流偏移时会溢出一个32位整数变量，可导致基于堆的破坏。要利用这个漏洞，攻击者不需要知道Snort探测器所运行的主机，只要精心构建TCP包就可能以Sn
