OESA-2026-1290 python-urllib3 security update

HTTP library with thread-safe connection pooling, file post support, sanity friendly, and more. Security Fixes: urllib3 is an HTTP client library for Python. urllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loadin...

urllib3: urllib3 Streaming API improperly handles highly compressed data

A decompression handling flaw has been discovered in urllib3. When streaming a compressed response, urllib3 can perform decoding or decompression based on the HTTP Content-Encoding header e.g., gzip, deflate, br, or zstd. The library must read compressed data from the network and decompress it...

lz4-java: lz4-java: Out-of-bounds memory operations lead to denial of service and information disclosure

A flaw was found in lz4-java. This vulnerability allows remote attackers to cause denial of service DoS and read adjacent memory via untrusted compressed input. This vulnerability affects only programs using the unsafe LZ4decompressfast API, known as the "fast" decompressor...
