Cisco NX-OS Software MPLS OAM Denial of Service (CVE-2021-1588)

A vulnerability in the MPLS Operation, Administration, and Maintenance OAM feature of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service DoS condition on an affected device. This vulnerability is due to improper input validation when an affected devi...

SUSE CVE-2010-4563

The Linux kernel, when using IPv6, allows remote attackers to determine whether a host is sniffing the network by sending an ICMPv6 Echo Request to a multicast address and determining whether an Echo Reply is sent, as demonstrated by thcping...

SUSE CVE-2014-0100

Race condition in the inetfragintern function in net/ipv4/inetfragment.c in the Linux kernel through 3.13.6 allows remote attackers to cause a denial of service use-after-free error or possibly have unspecified other impact via a large series of fragmented ICMP Echo Request packets to a system wi...

SUSE CVE-2020-17443

An issue was discovered in picoTCP 1.7.0. The code for creating an ICMPv6 echo replies doesn't check whether the ICMPv6 echo request packet's size is shorter than 8 bytes. If the size of the incoming ICMPv6 request packet is shorter than this, the operation that calculates the size of the ICMPv6...
