NVD Description

Note: Versions mentioned in the description apply only to the upstream kubeadm package and not the kubeadm package as distributed by Oracle. See How to fix? for Oracle:7 relevant fixed versions and status.

Envoy is a cloud-native high-performance proxy. In versions prior to 1.22.1 secompressors accumulate decompressed data into an intermediate buffer before overwriting the body in the decode/encodeBody. This may allow an attacker to zip bomb the decompressor by sending a small highly compressed payload. Maliciously constructed zip files may exhaust system memory and cause a denial of service. Users are advised to upgrade. Users unable to upgrade may consider disabling decompression.
