Design/Logic Flaw

An issue was discovered in the IPv6 protocol specification, related to ICMP Packet Too Big PTB messages. The scope of this CVE is all affected IPv6 implementations from all vendors. The security implications of IP fragmentation have been discussed at length in RFC6274 and RFC7739. An attacker can...

CVE-2016-10142

CVE-2016-10142 : The IPv6 fragmentation/atomic-fragment issue can cause a DoS (including kernel panic) by forging an ICMPv6 Packet Too Big message to trigger IPv6 atomic fragments, affecting IPv6 implementations across vendors. Connected docs confirm practical impact as DoS with possible kernel p...

Ubuntu 16.10 : linux-raspi2 vulnerabilities (USN-3170-2)

Andrey Konovalov discovered that the ipv6 icmp implementation in the Linux kernel did not properly check data structures on send. A remote attacker could use this to cause a denial of service system crash. CVE-2016-9919 Andrey Konovalov discovered that signed integer overflows existed in the...

BlackNurse Spoofed ICMP Denial Of Service Proof Of Concept Vulnerability

Blacknurse is a low bandwidth ICMP attack that is capable of doing denial of service to well known firewalls. Most ICMP attacks that we see are based on ICMP Type 8 Code 0 also called a ping flood attack. BlackNurse is based on ICMP with Type 3 Code 3 packets. We know that when a user has allowed...

Even A Single Computer Can Take Down Big Servers Using BlackNurse Attack

Yes, you only need a single laptop with a decent internet connection, rather a massive botnet, to launch overwhelming denial of service DoS attacks in order to bring down major Internet servers and modern-day firewalls. Researchers at TDC Security Operations Center have discovered a new attack...

BlackNurse Low-Volume DoS Attack Targets Firewalls

A type of denial of service attack relevant in the 1990s has resurfaced with surprising potency against modern-day firewalls. Dubbed a BlackNurse attack, the technique leverages a low-volume Internet Control Message Protocol ICMP -based attack on vulnerable firewalls made by Cisco, Palo Alto,...
