CVE-2020-15114: Fedoraproject Fedora

High severity, CVSS 7.7. EPSS: 1.2% chance of exploitation in the next 30 days.

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.

Affected products

• Fedoraproject Fedora: version 32 only
• Red Hat Etcd: from 3.3.0, before 3.3.23 (fixed in 3.3.23); from 3.4.0, before 3.4.10 (fixed in 3.4.10)
