Envoy is an open source edge and service proxy designed for cloud-native applications. From 1.23.0 until 1.35.11, 1.36.7, 1.37.3, and 1.38.1, a vulnerability has been identified in Envoy's zstd decompressor implementation ZstdDecompressorImpl. When zstd decompression is enabled, processing a...

fluent-plugin-opentelemetry Has Denial of Service (DoS) via Large Payloads and Decompression Bombs in `in_opentelemetry`

The fluent-plugin-opentelemetry plugin specifically the inopentelemetry HTTP input lacked strict size limits on incoming requests. It was discovered that the plugin read the entire request body and decompressed payloads into memory without enforcing maximum size thresholds. If the OpenTelemetry...

GHSA-XV9W-7V6Q-HPJH fluent-plugin-s3 Vulnerable to Denial of Service (DoS) via Decompression Bomb in `in_s3`

The fluent-plugin-s3 plugin specifically the ins3 input plugin supports reading and decompressing heavily compressed files such as gzip, lzma2, and lzop from Amazon S3. It was discovered that the plugin read the entire decompressed payload into memory at once without enforcing a strict size limit...
