Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Consul (github.com/hashicorp/consul) versions below 1.14.5 and from 1.15.0 up to but not including 1.15.3 are affected. A peer cluster that registers a service with the same name as a local service can corrupt Consul state, causing a denial of service. Upgrade to Consul 1.14.5 or 1.15.3. The source gives few details on the exact conditions required.
