redhat etcd CVE-2020-15114 vulnerability in Red Hat and Other Products
Published on August 6, 2020

Denial of Service in etcd

product logo product logo product logo
In etcd before versions 3.3.23 and 3.4.10, the etcd gateway is a simple TCP proxy to allow for basic service discovery and access. However, it is possible to include the gateway address as an endpoint. This results in a denial of service, since the endpoint can become stuck in a loop of requesting itself until there are no more available file descriptors to accept connections on the gateway.
