Vulnerability Description
Cisco PIX 6.3 and 7.0 allows remote attackers to cause a denial of service (blocked new connections) via spoofed TCP packets that cause the PIX to create embryonic connections that that would not produce a valid connection with the end system, including (1) SYN packets with invalid checksums, which do not result in a RST; or, from an external interface, (2) one byte of "meaningless data," or (3) a TTL that is one less than needed to reach the internal destination.

Vulnerability Title
Cisco PIX 6.3欺骗TCP SYN报文拒绝服务漏洞
Vulnerability Description
Cisco PIX是一款硬件防火墙解决方案。 Cisco PIX在处理畸形的TCP连接报文时存在漏洞，远程攻击者可能利用此漏洞对合法访问源造成拒绝服务攻击。如果通过PIX防火墙发送了有错误校验和的TCP SYN报文的话，PIX就会阻断使用相同源和目标TCP端口及IP地址的新TCP连接，直到大约2分钟后才会允许新的连接。因此攻击者可以发送有错误校验和的特制TCP报文，将源/目标IP和端口设置为合法的主机。一旦PIX防火墙接收了这样的报文，就无法同恶意报文中所指定的凭据建立新的TCP会话，默认时间为2分钟2秒
