CVE-2026-5438

A gzip decompression bomb vulnerability exists when Orthanc processes HTTP request with Content-Encoding: gzip. The server does not enforce limits on decompressed size and allocates memory based on attacker-controlled compression metadata. A specially crafted gzip payload can trigger excessive...

Security Bulletin: IBM Watson Speech Services Cartridge is vulnerable to a denial of service in the Base OS image package: Scrapy [CVE-2025-6176]

Summary IBM Watson Speech Services Cartridge is vulnerable to a denial of service in the Base OS image package: Scrapy, due to a flaw in its brotli decompression implementation. CVE-2025-6176. We have updated the base image used by our Speech Services and the following vulnerability has been...

CVE-2026-6100

A flaw was found in Python's decompression modules, including lzma.LZMADecompressor, bz2.BZ2Decompressor, and gzip.GzipFile. This vulnerability, a use-after-free, can occur if a program attempts to re-use a decompression object after a memory allocation error, especially when the system is...

FITS GZIP decompression bomb in Pillow

Impact Pillow did not limit the amount of GZIP-compressed data read when decoding a FITS image, making it vulnerable to decompression bomb attacks. A specially crafted FITS file could cause unbounded memory consumption, leading to denial of service OOM crash or severe performance degradation...

GHSA-WHJ4-6X5X-4V2J FITS GZIP decompression bomb in Pillow
