Changes with nginx 1.27.4 05 Feb 2025
*) Security: insufficient check in virtual servers handling with TLSv1.3
SNI allowed to reuse SSL sessions in a different virtual server, to
bypass client SSL certificates verification (CVE-2025-23419).
*) Feature: the "ssl_object_cache_inheritable", "ssl_certificate_cache",
"proxy_ssl_certificate_cache", "grpc_ssl_certificate_cache", and
"uwsgi_ssl_certificate_cache" directives.
*) Feature: the "keepalive_min_timeout" directive.
*) Workaround: "gzip filter failed to use preallocated memory" alerts
appeared in logs when using zlib-ng.
*) Bugfix: nginx could not build libatomic library using the library
sources if the --with-libatomic=DIR option was used.
*) Bugfix: QUIC connection might not be established when using 0-RTT;
the bug had appeared in 1.27.1.
*) Bugfix: nginx now ignores QUIC version negotiation packets from
clients.
*) Bugfix: nginx could not be built on Solaris 10 and earlier with the
ngx_http_v3_module.
*) Bugfixes in HTTP/3.
