ICMP messages to broadcast addresses are allowed, allowing for a Smurf attack that can cause a denial of service.
Jolt ICMP attack causes a denial of service in Windows 95 and Windows NT systems.
ip_input.c in BSD-derived TCP/IP implementations allows remote attackers to cause a denial of service (crash or hang) via crafted packets.
IP fragmentation denial of service in FreeBSD allows a remote attacker to cause a crash.
Teardrop IP denial of service.
Land IP denial of service.
Denial of Service vulnerability in BIND 8 Releases via maliciously formatted DNS messages.
In FreeBSD 12.0-STABLE before r350637, 12.0-RELEASE before 12.0-RELEASE-p9, 11.3-STABLE before r350638, 11.3-RELEASE before 11.3-RELEASE-p2, and 11.2-RELEASE before 11.2-RELEASE-p13, the bsnmp library is not properly validating the submitted length from a type-length-value encoding. A remote user could cause an out-of-bounds read or trigger a crash of the software such as bsnmpd resulting in a denial of service.
In FreeBSD 13.0-STABLE before n245765-bec0d2c9c841, 12.2-STABLE before r369859, 11.4-STABLE before r369866, 13.0-RELEASE before p1, 12.2-RELEASE before p7, and 11.4-RELEASE before p10, missing message validation in libradius(3) could allow malicious clients or servers to trigger denial of service in vulnerable servers or clients respectively.
The OSI networking kernel (sys/netiso) in NetBSD 1.6.1 and earlier does not use a BSD-required "PKTHDR" mbuf when sending certain error responses to the sender of an OSI packet, which allows remote attackers to cause a denial of service (kernel panic or crash) via certain OSI packets.
