N/A

The original design of TCP does not require that port numbers be assigned randomly (aka "Port randomization"), which makes it easier for attackers to forge ICMP error messages for specific TCP connections and cause a denial of service, as demonstrated using (1) blind connection-reset attacks with forged "Destination Unreachable" messages, (2) blind throughput-reduction attacks with forged "Source Quench" messages, or (3) blind throughput-reduction attacks with forged ICMP messages that cause the Path MTU to be reduced. NOTE: CVE-2004-0790, CVE-2004-0791, and CVE-2004-1060 have been SPLIT based on different attacks; CVE-2005-0065, CVE-2005-0066, CVE-2005-0067, and CVE-2005-0068 are related identifiers that are SPLIT based on the underlying vulnerability. While CVE normally SPLITs based on vulnerability, the attack-based identifiers exist due to the variety and number of affected implementations and solutions that address the attacks instead of the underlying vulnerabilities.

Microsoft Windows TCP/IP协议栈ICMP重置TCP连接漏洞(MS05-19/MS06-064)

Microsoft Windows是美国微软（Microsoft）公司发布的一系列操作系统。 Microsoft Windows的TCP/IP协议栈的ICMP协议处理模块存在漏洞，远程攻击者可能利用此漏洞重置服务器的TCP连接。 Microsoft Windows的ICMP协议处理模块没有充分检查某些类型ICMP消息的合法性，远程攻击者可以向受影响的服务器发送特制的ICMP消息导致服务器和客户端之间的已有TCP连接被重置。
