Server 2003 Path MTU Discovery Attack Vulnerability
Multiple TCP/IP and ICMP implementations when using Path MTU (PMTU) discovery (PMTUD) allow remote attackers to cause a denial of service (network throughput reduction for TCP connections) via forged ICMP ("Fragmentation Needed and Don't Fragment was Set") packets with a low next-hop MTU value aka the "Path MTU discovery attack." 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.
