Описание
A security issue was discovered in Kubernetes where a user may be able to redirect pod traffic to private networks on a Node. Kubernetes already prevents creation of Endpoint IPs in the localhost or link-local range, but the same validation was not performed on EndpointSlice IPs.

|---|---|---|---|---|
| kubernetes | fixed | 1.20.5+really1.20.2-1 | package |
Примечания
Server components no longer built since 1.20.5+really1.20.2-1, marking that as fixed version
The source package itself it still vulnerable, but custom rebuilds are not really a usecase here
