python-pillow: Pillow: Denial of Service via crafted PCF font data

A flaw was found in Pillow, a Python imaging library. A remote attacker could exploit this vulnerability by providing specially crafted PCF font data. This data, when processed, can lead to excessive memory allocation because the library does not properly check for decompression bombs. The primar...

CVE-2026-66913

The CVE-2026-66913 vulnerability affects Lookyloo when processing uploaded captures and API submissions containing gzip/zlib-compressed HAR data. The root cause is unbounded decompressed size during in-memory processing of ZIP/gzip/zlib content, enabling a zip bomb to exhaust memory and disrupt s...

UBUNTU-CVE-2026-15709

A flaw was found in libsoup's WebSocket implementation when using the permessage-deflate extension. The extension's decompression loop inflate processes data in chunks without enforcing an upper boundary limit on the output buffer size. While libsoup limits the incoming compressed frame size via...

Decompression-bomb safeguards bypassed when following HTTP redirects (streaming API)

Impacturllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once.urllib3 can perform decoding or decompression based on the HTTP Content-Encoding header e.g., gzip,...

Fluentd is Vulnerable to Denial of Service (DoS) via Gzip Decompression Bomb in `in_http` and `in_forward`

Fluentd's inhttp and inforward plugins support receiving gzip-compressed data. While Fluentd correctly enforces size limits on the incoming compressed payloads e.g., via bodysizelimit or chunksizelimit, it was discovered that there is no limit enforced on the size of the decompressed data. If 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...

urllib3: urllib3 vulnerable to decompression-bomb safeguard bypass when following HTTP redirects (streaming API)

A flaw was found in urllib3. When processing HTTP redirect responses during data streaming, the library automatically reads and decompresses the full response body without enforcing configured size limits. A malicious server can exploit this by serving an excessively compressed response, bypassin...
