I have just submitted for testing
https://bodhi.fedoraproject.org/updates/FEDORA-EPEL-2024-ce142428af,
which updates llhttp in EPEL9 from 9.1.3 to 9.2.1 and fixes
CVE-2024-27982[1], an HTTP request smuggling vulnerability. Version
9.2.0 also included a number of bug fixes[2]. This is an
ABI-incompatible update, and the SONAME version changes.
Because the EPEL Steering Committee has previously approved a permanent
exception for incompatible upgrades of llhttp, I have bypassed the usual
proposal and discussion of this update on the epel-devel mailing list.
However, I am following the other parts of the incompatible updates
process: this announcement, at least one week in testing with auto-push
disabled, and a follow-up announcement on this list once I have pushed
the update to stable.
The only package in EPEL9 that uses llhttp is python-aiohttp; the update
also backports support for llhttp 9.2.1 to the current aiohttp release,
3.9.3. I expect that the aiohttp project will soon release a compatible
patch release 3.9.4 that directly supports llhttp 9.2.1.
If you have software not packaged in EPEL9 that depends directly on
llhttp, you will need to rebuild it due to the ABI changes. It is
possible that source code changes may be required if (like
python-aiohttp) you use almost the entire API of llhttp, or if you have
very thorough tests that reveal small changes in llhttp’s behavior.
Straightforward uses of llhttp are very likely to recompile without
modification.
I have no plans to attempt a build of llhttp or any update of
python-aiohttp in EPEL8.
