Astra Linux - уязвимость в curl

curl 7.84.0 supports “chained” HTTP compression algorithms, which means that a server response can be compressed multiple times, possibly using different algorithms. The number of allowable “links” in this “decompression chain” is unlimited, allowing a malicious server to insert virtually an...

SUSE-SU-2026:20443-1 Security update for python-urllib3

This update for python-urllib3 fixes the following issues: - CVE-2025-66471: excessive resource consumption via decompression of highly compressed data in Streaming API bsc1254867. - CVE-2025-66418: resource exhaustion via unbounded number of links in the decompression chain bsc1254866...

urllib3: urllib3: Unbounded decompression chain leads to resource exhaustion

A flaw was found in urllib3 Python library that could lead to a Denial of Service condition. A remote, malicious server can exploit this flaw by responding to a client request with an HTTP message that uses an excessive number of chained compression algorithms. This unlimited decompression chain...

Amazon Linux 2023 : python3-urllib3 (ALAS2023-2026-1418)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1418 advisory. urllib3 is a user-friendly HTTP client library for Python. Starting in version 1.24 and prior to 2.6.0, the number of links in the decompression chain was unbounded allowing a malicious server...

CVE-2026-22036

Undici (HTTP/1.1 client for Node.js) contains a vulnerability in its decompression chain handling. Before versions 7.18.0 and 6.23.0, the chain can have an unbounded number of links, and the default maxHeaderSize allows a malicious server to insert thousands of compression steps, causing high CPU...

urllib3 allows an unbounded number of links in the decompression chain

Impact urllib3 supports chained HTTP encoding algorithms for response content according to RFC 9110 e.g., Content-Encoding: gzip, zstd. However, the number of links in the decompression chain was unbounded allowing a malicious server to insert a virtually unlimited number of compression steps...

CVE-2025-66418 urllib3 allows an unbounded number of links in the decompression chain

urllib3 is a user-friendly HTTP client library for Python. Starting in version 1.24 and prior to 2.6.0, the number of links in the decompression chain was unbounded allowing a malicious server to insert a virtually unlimited number of compression steps leading to high CPU usage and massive memory...

An allocation of resources without limits or throttling vulnerability exists in curl <v7.88.0 based on the "chained" HTTP compression algorithms meaning that a server response can be compressed multiple times and potentially with differentalgorithms. The number of acceptable "links" in this "decompression chain" wascapped but the cap was implemented on a per-header basis allowing a maliciousserver to insert a virtually unlimited number of compression steps simply byusing many headers. The use of such a decompression chain could result in a "malloc bomb" making curl end up spending enormous amounts of allocated heap memory or trying to and returning out of memory errors.
