Multiple Vendor ICMP Message Handling - 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...

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-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...

CVE-2005-0067

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...

CVE-2005-0068

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...

CVE-2005-0066

The original design of TCP does not check that the TCP Acknowledgement number in an ICMP error message generated by an intermediate router is within the range of possible values for data that has already been acknowledged aka "TCP acknowledgement number checking", which makes it easier for...

TCP Vulnerabilities in Multiple Non-IOS Cisco Products

A vulnerability in the Transmission Control Protocol TCP specification RFC793 has been discovered by an external researcher. The successful exploitation enables an adversary to reset any established TCP connection in a much shorter time than was previously discussed publicly. Depending on the...

CVE-1999-1291

TCP/IP implementation in Microsoft Windows 95, Windows NT 4.0, and possibly others, allows remote attackers to reset connections by forcing a reset RST via a PSH ACK or other means, obtaining the target's last sequence number from the resulting packet, then spoofing a reset to the target...
