CVE-2022-29225: Envoyproxy Envoy

High severity, CVSS 7.5. EPSS: 1.6% chance of exploitation in the next 30 days.

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.

Affected products

• Envoyproxy Envoy: before 1.22.1 (fixed in 1.22.1)
