Description
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.
Weaknesses (CWE)
- CWE-400 — Uncontrolled Resource Consumption
- CWE-409 — Improper Handling of Highly Compressed Data (Data Amplification)
