NGINX Plus and NGINX Open Source have a vulnerability in the ngx_stream_ssl_module module due to the improper handling of revoked certificates when configured with the ssl_verify_client on and ssl_ocsp on directives, allowing the TLS handshake to succeed even after an OCSP check identifies the certificate as revoked. Note: Software versions which have reached End of

CVE-2009-3896 [MEDIUM] CVE-2009-3896: nginx - src/http/ngx_http_parse.c in nginx (aka Engine X) 0.1.0 through 0.4.14, 0.5.x be... src/http/ngx_http_parse.c in nginx (aka Engine X) 0.1.0 through 0.4.14, 0.5.x before 0.5.38, 0.6.x before 0.6.39, 0.7.x before 0.7.62, and 0.8.x before 0.8.14 allows remote attackers to cause a denial of service (NULL pointer dereference and worker process crash) via a long URI.

When NGINX Plus or NGINX OSS are configured to use the HTTP/3 QUIC module and the network infrastructure supports a Maximum Transmission Unit (MTU) of 4096 or greater without fragmentation, undisclosed QUIC packets can cause NGINX worker processes to leak previously freed memory.

CVE-2025-23419 [MEDIUM] CVE-2025-23419: nginx - When multiple server blocks are configured to share the same IP address and port... When multiple server blocks are configured to share the same IP address and port, an attacker can use session resumption to bypass client certificate authentication requirements on these servers. This vulnerability arises when TLS Session Tickets https://nginx.org/en/docs/http/ngx_http_ssl_module.html#ssl_session_ticket_key are used and/or the SSL session cache http

CVE-2024-31079 [MEDIUM] CVE-2024-31079: nginx - When NGINX Plus or NGINX OSS are configured to use the HTTP/3 QUIC module, undis... When NGINX Plus or NGINX OSS are configured to use the HTTP/3 QUIC module, undisclosed HTTP/3 requests can cause NGINX worker processes to terminate or cause other potential impact. This attack requires that a request be specifically timed during the connection draining process, which the attacker has no visibility and limited influence over. Scope: local bookworm:

CVE-2025-53859 [MEDIUM] CVE-2025-53859: nginx - NGINX Open Source and NGINX Plus have a vulnerability in the ngx_mail_smtp_modul... NGINX Open Source and NGINX Plus have a vulnerability in the ngx_mail_smtp_module that might allow an unauthenticated attacker to over-read NGINX SMTP authentication process memory; as a result, the server side may leak arbitrary bytes sent in a request to the authentication server. This issue happens during the NGINX SMTP authentication process and requires the att

CVE-2024-7347 [MEDIUM] CVE-2024-7347: nginx - NGINX Open Source and NGINX Plus have a vulnerability in the ngx_http_mp4_module... NGINX Open Source and NGINX Plus have a vulnerability in the ngx_http_mp4_module, which might allow an attacker to over-read NGINX worker memory resulting in its termination, using a specially crafted mp4 file. The issue only affects NGINX if it is built with the ngx_http_mp4_module and the mp4 directive is used in the configuration file. Additionally, the attack is p

CVE-2026-28753 [MEDIUM] CVE-2026-28753: nginx - NGINX Plus and NGINX Open Source have a vulnerability in the ngx_mail_smtp_modul... NGINX Plus and NGINX Open Source have a vulnerability in the ngx_mail_smtp_module module due to the improper handling of CRLF sequences in DNS responses. This allows an attacker-controlled DNS server to inject arbitrary headers into SMTP upstream requests, leading to potential request manipulation. Note: Software versions which have reached End of Technical Support

CVE-2012-4929 [LOW] CVE-2012-4929: apache2 - The TLS protocol 1.2 and earlier, as used in Mozilla Firefox, Google Chrome, Qt,... The TLS protocol 1.2 and earlier, as used in Mozilla Firefox, Google Chrome, Qt, and other products, can encrypt compressed data without properly obfuscating the length of the unencrypted data, which allows man-in-the-middle attackers to obtain plaintext HTTP headers by observing length differences during a series of guesses in which a string in an HTTP request potenti
