Changes with nginx 1.30.3
*) Security: a heap memory buffer overflow might occur in a worker
process when using a configuration with "ignore_invalid_headers off;"
and "large_client_header_buffers" with large configured values when
proxying a specially crafted request to HTTP/2 or gRPC backend,
allowing an attacker to cause worker process memory corruption or
segmentation fault in a worker process (CVE-2026-42055).
*) Security: a heap memory buffer overread might occur in a worker
process while handling a specially sent response with decoding from
UTF-8 via the "charset_map" directive, allowing an attacker to cause
a limited disclosure of worker proccess memory or segmentation fault
in a worker process (CVE-2026-48142).

Changes with nginx 1.30.2
*) Security: a heap memory buffer overflow might occur in a worker
process when using a configuration with overlapping captures in
ngx_http_rewrite_module, potentially resulting in arbitrary code
execution (CVE-2026-9256).

Changes with nginx 1.30.1
*) Security: when using the "proxy_set_body" directive, an attacker
might inject data in the proxied request to an HTTP/2 backend
(CVE-2026-42926).
*) Security: a heap memory buffer overflow might occur in a worker
process while handling a specially crafted request by
ngx_http_rewrite_module, potentially resulting in arbitrary code
execution (CVE-2026-42945).
*) Security: a heap memory buffer overread might occur in a worker
process while handling a specially crafted response by
ngx_http_scgi_module or ngx_http_uwsgi_module, allowing an attacker
to cause a disclosure of worker process memory or segmentation fault
in a worker process (CVE-2026-42946).
*) Security: a heap memory buffer overread might occur in a worker
process while handling a specially sent response with decoding from
UTF-8 via the "charset_map" directive, allowing an attacker to cause
a limited disclosure of worker proccess memory or segmentation fault
in a worker process (CVE-2026-42934).
*) Security: when using HTTP/3, processing of connection migration might
cause new QUIC streams to receive a new client address before
validation, allowing an attacker to cause address spoofing
(CVE-2026-40460).
*) Security: use-after-free might occur during DNS server response
processing if the "ssl_ocsp" directive was used, allowing an attacker
to cause worker process memory corruption or segmentation fault in a
worker process (CVE-2026-40701).
*) Bugfix: connections with HTTP/2 backends might not be cached when
using the "proxy_set_body" or "proxy_pass_request_body" directives.
*) Bugfix: proxied HTTP/0.9, SCGI, or uWSGI responses might be
transferred incorrectly if the first line was not fully read.

Changes:
*) Security: a buffer overflow might occur while handling a COPY or MOVE
request in a location with "alias", allowing an attacker to modify
the source or destination path outside of the document root
(CVE-2026-27654).
*) Security: processing of a specially crafted mp4 file by the
ngx_http_mp4_module on 32-bit platforms might cause a worker process
crash, or might have potential other impact (CVE-2026-27784).
*) Security: processing of a specially crafted mp4 file by the
ngx_http_mp4_module might cause a worker process crash, or might have
potential other impact (CVE-2026-32647).
*) Security: a segmentation fault might occur in a worker process if the
CRAM-MD5 or APOP authentication methods were used and authentication
retry was enabled (CVE-2026-27651).
*) Security: an attacker might use PTR DNS records to inject data in
auth_http requests, as well as in the XCLIENT command in the backend
SMTP connection (CVE-2026-28753).
*) Security: SSL handshake might succeed despite OCSP rejecting a client
certificate in the stream module (CVE-2026-28755).
*) Feature: the "multipath" parameter of the "listen" directive.
*) Feature: the "local" parameter of the "keepalive" directive in the
"upstream" block.
*) Change: now the "keepalive" directive in the "upstream" block is
enabled by default.
*) Change: now ngx_http_proxy_module supports keepalive by default; the
default value for "proxy_http_version" is "1.1"; the "Connection"
proxy header is not sent by default anymore.
*) Bugfix: an invalid HTTP/2 request might be sent after switching to
the next upstream if buffered body was used in the
ngx_http_grpc_module.

as installation also finishes correctly without sytemd-tmpfiles
