Fedora 40: FEDORA-2025-bd59b39ab6 moderate: python-h11 malformed encoding

Backport upstream fix for CVE-2025-43859. -------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2025-bd59b39ab6 2025-05-11 01:42:02.655172+00:00 -------------------------------------------------------------------------------- Name : python-h11 Product : Fedora 40 Version : 0.14.0 Release : 7.fc40 URL : https://github.com/python-hyper/h11 Summary : A pure-Python, bring-your-own-I/O implementation of HTTP/1.1 Description : This is a little HTTP/1.1 library written from scratch in Python, heavily inspired by hyper-h2. It is a "bring-your-own-I/O" library; h11 contains no IO code whatsoever. This means you can hook h11 up to your favorite network API, and that could be anything you want: synchronous, threaded, asynchronous, or your own implementation of RFC 6214 -- h11 will not judge you. This also means that h11 is not immediately useful out of the box: it is a toolkit for building programs that speak HTTP, not something that could directly replace requests or twisted.web or whatever. But h11 makes it much easier to implement something like requests or twisted.web. -------------------------------------------------------------------------------- Update Information: Backport upstream fix for CVE-2025-43859 -------------------------------------------------------------------------------- ChangeLog: * Fri May 2 2025 Robby Callicotte - 0.14.0-7 - Backport upstream fix for CVE-2025-43859 * Sat Jan 18 2025 Fedora Release Engineering - 0.14.0-6 - Rebuilt for https://fedoraproject.org/wiki/Fedora_42_Mass_Rebuild * Fri Jul 19 2024 Fedora Release Engineering - 0.14.0-5 - Rebuilt for https://fedoraproject.org/wiki/Fedora_41_Mass_Rebuild * Fri Jun 7 2024 Python Maint - 0.14.0-4 - Rebuilt for Python 3.13 -------------------------------------------------------------------------------- References: [ 1 ] Bug #2362285 - CVE-2025-43859 python-h11: h11 accepts some malformedChunked-Encoding bodies [fedora-40] https://bugzilla.redhat.com/show_bug.cgi?id=2362285 -------------------------------------------------------------------------------- This update can be installed with the "dnf" update program.
