NVD Description

Note: Versions mentioned in the description apply only to the upstream golang-bin package and not the golang-bin package as distributed by Oracle. See How to fix? for Oracle:9 relevant fixed versions and status.

Handshake messages, such as KeyUpdate, are always considered as state-advancing, regardless of whether a handshake has been completed or not. As a result, a malicious client can keep sending KeyUpdate messages to force the server to keep performing key derivation operations indefinitely.
