Denial of Service (DoS)

Overview ultimate-sitemap-parser is an A performant library for parsing and crawling sitemaps Affected versions of this package are vulnerable to Denial of Service DoS through the gunzip process. An attacker can exhaust system memory or crash the application by serving a specially crafted...

GHSA-8823-QG2X-PV9F Ultimate Sitemap Parser (USP): Gzip Decompression Bomb Bypasses Sitemap Size Limit

Gzip Decompression Bomb Bypasses Sitemap Size Limit Summary ultimate-sitemap-parser enforces a 100 MiB size limit on sitemap responses, but applies it only to the compressed bytes received over the network. When a .gz sitemap is fetched, usp/helpers.py:239 calls gziplib.decompressdata with no...

Python Library Tornado < 6.5.6 Multiple Vulnerabilities

The version of the Tornado Python library installed on the remote host is prior to 6.5.6. It is, therefore, affected by multiple vulnerabilities: - When SimpleAsyncHTTPClient follows a 3xx redirect, it shallow-copies the original HTTPRequest, rewrites the URL, decrements maxredirects, and removes...

GHSA-MGF9-4VPG-HJ56 tornado AsyncHTTPClient accumulates decompressed chunks without size limit (gzip bomb)

Tornado's gzip decompression routines work in limited-size chunks, but have no overall limit for the total size of decompressed chunks that they will accumulate There has always been a limit for the total compressed size. This allows a malicious server to consume effectively unlimited amounts of...

CVE-2026-53430: Improper Handling of Highly Compressed Data (Data Amplification)

Improper Handling of Highly Compressed Data Data Amplification vulnerability in elixir-grpc grpc GRPC.Compressor.Gzip, GRPC.Message modules allows a denial of service via a gzip decompression bomb. This vulnerability is associated with program files lib/grpc/compressor/gzip.ex, lib/grpc/message.e...

github.com/sigstore/rekor: Rekor: Denial of Service due to unbounded gzip decompression in Alpine APK parsing

A flaw was found in Rekor. The Package.Unmarshal function, which processes Alpine Package Keep APK files, decompresses gzip streams without limiting the total decompressed size. A remote attacker can exploit this by crafting a malicious APK file with a high compression ratio, causing the server t...

Pillow: Pillow: Denial of Service via decompression bomb in FITS image processing

A flaw was found in Pillow, a Python imaging library. This vulnerability allows a remote attacker to trigger a denial of service DoS by providing a specially crafted FITS image file. The library's failure to limit the amount of GZIP-compressed data during decoding can lead to unbounded memory...
