CVE-2004-1060
CVE-2004-1060 enables a denial-of-service via forged ICMP PMTU-discovery packets that degrade TCP throughput. Connected advisories show affected BIG-IP products and data-plane components; vulnerable versions include BIG-IP LTM/AAM/AFM/etc. for 10.x–11.x releases (e.g., 11.0.0–11.6.0, 10.0.0–10.2....
Multiple Vendor ICMP Implementation - Malformed Path MTU Denial of Service
source: https://www.securityfocus.com/bid/13124/info Multiple vendor implementations of TCP/IP Internet Control Message Protocol ICMP are reported prone to several denial-of-service attacks. ICMP is employed by network nodes to determine certain automatic actions to take based on network failures...
TCP/IP implementations do not adequately validate ICMP error messages
Overview Multiple TCP/IP implementations do not adequately validate ICMP error messages. A remote attacker could cause TCP connections to drop or be degraded using spoofed ICMP error messages. Description A number of widely accepted Internet standards describe different aspects of the relationshi...
CVE-2005-0068
CVE-2005-0068 is attack-based and tied to ICMP handling flaws (forgeable ICMP errors affecting TCP/Path MTU) with related CVEs (2004-0790/0791/1060). Connected documents provide concrete details: ICMP authentication gaps enable denial-of-service via spoofed messages (Destination Unreachable, Sour...

Technical details for CVE-2005-0067 (affected software/versions, root cause, impact, and fixes) are not publicly available in the provided Connected documents. Monitor for updates.
CVE-2005-0065
The original design of TCP does not check that the TCP sequence number in an ICMP error message is within the range of sequence numbers for data that has been sent but not acknowledged aka "TCP sequence number checking", which makes it easier for attackers to forge ICMP error messages for specifi...
CVE-2004-0257
OpenBSD 3.4 and NetBSD 1.6 and 1.6.1 allow remote attackers to cause a denial of service crash by sending an IPv6 packet with a small MTU to a listening port and then issuing a TCP connect to that port...

CVE-2004-1060
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...

CVE-2001-0323
The ICMP path MTU PMTU discovery feature in various UNIX systems allows remote attackers to cause a denial of service by spoofing "ICMP Fragmentation needed but Don't Fragment DF set" packets between two target hosts, which could cause one host to lower its MTU when transmitting to the other host...

CVE-2001-0323
The CVE-2001-0323 entry describes a denial-of-service risk in the ICMP path MTU (PMTU) discovery feature used by various UNIX systems. The underlying issue is that remote attackers can spoof ICMP messages of type “Fragmentation needed but Don’t Fragment (DF) set” between two hosts, potentially ca...
Re: ICMP fragmentation required but DF set problems.
This is a valid method, and known, to slow down a link between two hosts. In my paper "ICMP Usage In Scanning" currently version 2.5 Appendix B: ICMP "Fragmentation Needed but the Don't Fragment Bit was set" and the Path MTU Discovery Process Page 132, I have outlined what should be done accordin...
