The release of the main branch nginx 1.27.1 has been formed, continuing the development of new features, alongside the release of the concurrently supported stable branch nginx 1.22.1, which only receives changes related to fixing serious bugs and vulnerabilities. The updates address a vulnerability (CVE-2024-7347) in the ngx_http_mp4_module, leading to a crash of the worker process while processing a specially crafted MP4 file. The issue has been present since version 1.5.13 when compiling nginx with the ngx_http_mp4_module (which is not compiled by default) and using the mp4 directive in the configuration. To fix the vulnerability in older versions, a patch can be applied.
In addition to the vulnerability in the release of nginx 1.27.1, errors in the implementation of the HTTP/3 protocol have also been resolved, the stream module handler has been downgraded to optional, and the issue of ignoring new HTTP/2 connections during graceful worker process termination has been addressed.
