The original design of ICMP does not require authentication for host-generated ICMP error messages, 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。
