Security Bulletin: IBM Watson Speech Services Cartridge is vulnerable to a denial of service in Pillow [CVE-2026-40192]

Summary IBM Watson Speech Services Cartridge is vulnerable to a denial of service in Pillow, due to a failure to limit the amount of GZIP-compressed data read when decoding a FITS image, making them vulnerable to decompression bomb attack CVE-2026-40192. Pillow is used in our speech runtimes. Thi...

Astra Linux – Vulnerability in curl

There is a vulnerability in curl v7.88.0 where resource allocation without limits or throttling exists. This vulnerability stems from the “chained” HTTP compression algorithms. This means that a server’s response can be compressed multiple times, possibly using different algorithms. The number of...

Astra Linux – Vulnerability in Python 3.7

The lib/zipfile.py module in Python, as of version 3.7.2, allows remote attackers to cause a denial of service resource consumption through a ZIP bomb attack...

CVE-2026-42587

Netty CVE-2026-42587 affects HttpContentDecompressor and DelegatingDecompressorFrameListener. Before 4.2.13.Final and 4.1.133.Final, maxAllocation is enforced for gzip/deflate but ignored for br, zstd, or snappy, allowing an attacker to bypass the decompression limit via Content-Encoding: br and ...

CVE-2026-42587 Netty: HttpContentDecompressor maxAllocation bypass via Content-Encoding: br/zstd/snappy enables decompression bomb DoS

Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final and 4.1.133.Final, HttpContentDecompressor accepts a maxAllocation parameter to limit decompression buffer size and prevent decompression bomb attacks. This limit is correctly enforced for gzip and deflate...

CVE-2026-44432 urllib3: Decompression-bomb safeguards bypassed in parts of the streaming API

urllib3 is an HTTP client library for Python. From 2.6.0 to before 2.7.0, urllib3 could decompress the whole response instead of the requested portion 1 during the second HTTPResponse.readamt=N call when the response was decompressed using the official Brotli library or 2 when...

CVE-2026-44432

CVE-2026-44432 affects urllib3 before 2.7.0, where the library could decompress the entire response during HTTPResponse.read or drain_conn, leading to high CPU and memory usage when handling highly compressed data. Affected versions: 2.6.0 up to (but not including) 2.7.0. Impact described as pote...

CVE-2026-31248

Docling's METS GBS backend is vulnerable to XML Entity Expansion XXE attacks thru 2.61.0. The backend extracts and validates XML files from .tar.gz archives using etree.fromstring without disabling entity resolution. An attacker can craft a malicious XML file with nested entity definitions XML Bo...

urllib3: Decompression-bomb safeguards bypassed in parts of the streaming API

Impact urllib3'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 decompression based on the HTTP Content-Encoding header e.g., gzip, deflate, br, or...

Decompression Bomb

Overview urllib3 is a HTTP library with thread-safe connection pooling, file post, and more. Affected versions of this package are vulnerable to Decompression Bomb either in HTTPResponse.read when Brotli is in use, or when HTTPResponse.drainconn is called after partial decompression has begun. An...
