CVE-2022-23606
This infinite recursion causes Envoy to crash.
MEDIUM 6.5EPSS 1.02%
Does this matter?
Lower severity and a low EPSS score (1.02%). Track it; it rarely justifies an emergency change on its own.
Description
Envoy is an open source edge and service proxy, designed for cloud-native applications. When a cluster is deleted via Cluster Discovery Service (CDS) all idle connections established to endpoints in that cluster are disconnected. A recursion was introduced in the procedure of disconnecting idle connections that can lead to stack exhaustion and abnormal process termination when a cluster has a large number of idle connections. This infinite recursion causes Envoy to crash. Users are advised to upgrade.
