NGINX 1.31.1 Mainline with Brotli, TLS 1.3, OpenSSL 4.0.0, HTTP/2 and HTTP/3 for Red Hat Enterprise Linux, CentOS, Rocky, Oracle, Alma Linux EL7/EL8/EL9/EL10

nginx 1.31.1 Mainline with HTTP/3 support added to EL7, EL8, EL9 and EL10 repositories. Brotli compression module from Google, http2, ngx_cache_purge and ngx_http_geoip2 modules are built in. OpenSSL is built dynamically using official OpenSSL 4.0.0 with QUIC support.

Major changes:

*) 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). Thanks to Mufeed VH of Winfunc Research.

nginx 1.30.2 Stable with HTTP/3 support added to EL7, EL8, EL9 and EL10 repositories. Brotli compression module from Google, http2, ngx_cache_purge and ngx_http_geoip2 modules are built in. OpenSSL is built dynamically using official OpenSSL 4.0.0 with QUIC support.

Major changes:

Fix for buffer overflow vulnerability in the ngx_http_rewrite_module (CVE-2026-9256).

NGINX 1.31.0 Mainline with Brotli, TLS 1.3, OpenSSL 4.0.0, HTTP/2 and HTTP/3 for Red Hat Enterprise Linux, CentOS, Rocky, Oracle, Alma Linux EL7/EL8/EL9/EL10

nginx 1.31.0 Mainline with HTTP/3 support added to EL7, EL8, EL9 and EL10 repositories. Brotli compression module from Google, http2, ngx_cache_purge and ngx_http_geoip2 modules are built in. OpenSSL is built dynamically using official OpenSSL 4.0.0 with QUIC support.

Major changes:

    *) 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).
       Thanks to Mufeed VH of Winfunc Research.

    *) 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).
       Thanks to Leo Lin.

    *) 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).
       Thanks to Leo Lin.

    *) 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).
       Thanks to David Carlier.

    *) 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).
       Thanks to Rodrigo Laneth.

    *) 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).
       Thanks to Leo Lin.

    *) Change: now nginx rejects HTTP/2 and HTTP/3 requests with the
       "Connection", "Proxy-Connection", "Keep-Alive", "Transfer-Encoding",
       "Upgrade" header lines, and "TE" with any value other than
       "trailers".

    *) Change: the ngx_http_dav_module now rejects a COPY or MOVE requests
       when the source and destination resources are the same or have a
       parent-child collection relationship.

    *) Change: the logging level of the "invalid alert" and "record layer
       failure" SSL errors, and of the "SSL alert number N" for any alert
       numbers has been lowered from "crit" to "info".

    *) Change: now the "sticky" module can be disabled with the
       --without-http_upstream_sticky_module configure option; the
       --without-http_upstream_sticky configure option is deprecated.

    *) Feature: the ngx_http_tunnel_module; support for authenticating to
       proxies in the "auth_basic", "satisfy", and "auth_delay" directives.

    *) Feature: the "least_time" directive inside the "upstream" block.

    *) Feature: the "proxy_ssl_alpn" directive in the stream module.

    *) 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.

openssl 4.0.0 rpms released

openssl 4.0.0 rpms released and added to all supported platforms (Alma Linux, Rocky Linux, Red Hat Enterprise Linux RHEL, Oracle Linux).

OpenSSL 4.0.0 is a feature release adding significant new functionality to OpenSSL. This release incorporates the following potentially significant or incompatible changes:

– Removed extra leading ’00:’ when printing key data such as an RSA modulus in hexadecimal format where the first (most significant) byte is >= 0x80. – Standardized the width of hexadecimal dumps to 24 bytes for signatures (to stay within the 80 characters limit) and 16 bytes for everything else. – Lower bounds checks are now enforced when using `PKCS5_PBKDF2_HMAC` API with FIPS provider. – Added AKID verification checks when `X509_V_FLAG_X509_STRICT` is set. – Augmented CRL verification process with several additional checks. – `libcrypto` no longer cleans up globally allocated data via `atexit()`. – `BIO_snprintf()` now uses `snprintf()` provided by libc instead of internal implementation. – `OPENSSL_cleanup()` now runs in a global destructor, or not at all by default. – `ASN1_STRING` has been made opaque. – Signatures of numerous API functions, including those that are related to X509 processing, are changed to include `const` qualifiers for argument and return types, where suitable. – Deprecated `X509_cmp_time()`, `X509_cmp_current_time()`, and `X509_cmp_timeframe()` in favor of `X509_check_certificate_times()`. – Removed support for the SSLv2 Client Hello. – Removed support for SSLv3. SSLv3 has been deprecated since 2015, and OpenSSL had it disabled by default since version 1.1.0 (2016). – Removed support for engines. The `no-engine` build option and the `OPENSSL_NO_ENGINE` macro are always present. – Support of deprecated elliptic curves in TLS according to RFC 8422 was disabled at compile-time by default. To enable it, use the `enable-tls-deprecated-ec` configuration option. – Support of explicit EC curves was disabled at compile-time by default. To enable it, use the `enable-ec_explicit_curves` configuration option. – Removed `c_rehash` script tool. Use `openssl rehash` instead. – Removed the deprecated `msie-hack` option from the `openssl ca` command. – Removed `BIO_f_reliable()` implementation without replacement. It was broken since 3.0 release without any complaints. – Removed deprecated support for custom `EVP_CIPHER`, `EVP_MD`, `EVP_PKEY`, and `EVP_PKEY_ASN1` methods. – Removed deprecated fixed SSL/TLS version method functions. – Removed deprecated functions `ERR_get_state()`, `ERR_remove_state()` and `ERR_remove_thread_state()`. The `ERR_STATE` object is now always opaque. – Dropped `darwin-i386{,-cc}` and `darwin-ppc{,64}{,-cc}` targets from Configurations. This release adds the following new features: – Support for Encrypted Client Hello (ECH, RFC 9849). See `doc/designs/ech-api.md` for details. – Support for RFC 8998, signature algorithm `sm2sig_sm3`, key exchange group `curveSM2`, and tls-hybrid-sm2-mlkem post-quantum group `curveSM2MLKEM768`. – cSHAKE function support as per SP 800-185. – “ML-DSA-MU” digest algorithm support. – Support for SNMP KDF and SRTP KDF. – FIPS self tests can now be deferred and run as needed when installing the FIPS module with the `-defer_tests` option of the `openssl fipsinstall` command. – Support for using either static or dynamic VC runtime linkage on Windows. – Support for negotiated FFDHE key exchange in TLS 1.2 in accordance with RFC 7919. RFC 8422: RFC 9849: RFC 8998: SP 800-185: RFC 7919:

.so Suffix changed from 81.3 to 81.4 (/usr/lib64/libcrypto.so.81.4.0.0, /usr/lib64/libcrypto.so.81.4 -> libcrypto.so.81.4.0.0, /usr/lib64/libssl.so.81.4.0.0, /usr/lib64/libssl.so.81.4 -> libssl.so.81.4.0.0).

We continue to build libs with QUIC support as a separate non-conflicting package openssl-quic-libs, with separate .so.81.4 suffixing to avoid conflicts with the official .so.X.
