| CVE-2009-3555 | 8 Apache, Canonical, Debian and 5 more | 8 Http Server, Ubuntu Linux, Debian Linux and 5 more | 2026-05-27 | 5.8 MEDIUM | 9.8 CRITICAL |
| The TLS protocol, and the SSL protocol 3.0 and possibly earlier, as used in Microsoft Internet Information Services (IIS) 7.0, mod_ssl in the Apache HTTP Server 2.2.14 and earlier, OpenSSL before 0.9.8l, GnuTLS 2.8.5 and earlier, Mozilla Network Security Services (NSS) 3.12.4 and earlier, multiple Cisco products, and other products, does not properly associate renegotiation handshakes with an existing connection, which allows man-in-the-middle attackers to insert data into HTTPS sessions, and possibly other types of sessions protected by TLS or SSL, by sending an unauthenticated request that is processed retroactively by a server in a post-renegotiation context, related to a "plaintext injection" attack, aka the "Project Mogul" issue. | |||||
| CVE-2017-3169 | 1 Apache | 1 Http Server | 2026-05-13 | 7.5 HIGH | 9.8 CRITICAL |
| In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, mod_ssl may dereference a NULL pointer when third-party modules call ap_hook_process_connection() during an HTTP request to an HTTPS port. | |||||
| CVE-2014-3250 | 3 Apache, Puppet, Redhat | 3 Http Server, Puppet, Linux | 2026-05-13 | 4.0 MEDIUM | 6.5 MEDIUM |
| The default vhost configuration file in Puppet before 3.6.2 does not include the SSLCARevocationCheck directive, which might allow remote attackers to obtain sensitive information via a revoked certificate when a Puppet master runs with Apache 2.4. | |||||
| CVE-2017-7668 | 6 Apache, Apple, Debian and 3 more | 13 Http Server, Mac Os X, Debian Linux and 10 more | 2026-05-13 | 5.0 MEDIUM | 7.5 HIGH |
| The HTTP strict parsing changes added in Apache httpd 2.2.32 and 2.4.24 introduced a bug in token list parsing, which allows ap_find_token() to search past the end of its input string. By maliciously crafting a sequence of request headers, an attacker may be able to cause a segmentation fault, or to force ap_find_token() to return an incorrect value. | |||||
| CVE-2016-8743 | 4 Apache, Debian, Netapp and 1 more | 12 Http Server, Debian Linux, Clustered Data Ontap and 9 more | 2026-05-13 | 5.0 MEDIUM | 7.5 HIGH |
| Apache HTTP Server, in all releases prior to 2.2.32 and 2.4.25, was liberal in the whitespace accepted from requests and sent in response lines and headers. Accepting these different behaviors represented a security concern when httpd participates in any chain of proxies or interacts with back-end application servers, either through mod_proxy or using conventional CGI mechanisms, and may result in request smuggling, response splitting and cache pollution. | |||||
| CVE-2017-7679 | 1 Apache | 1 Http Server | 2026-05-13 | 7.5 HIGH | 9.8 CRITICAL |
| In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, mod_mime can read one byte past the end of a buffer when sending a malicious Content-Type response header. | |||||
| CVE-2017-9798 | 2 Apache, Debian | 2 Http Server, Debian Linux | 2026-05-13 | 5.0 MEDIUM | 7.5 HIGH |
| Apache httpd allows remote attackers to read secret data from process memory if the Limit directive can be set in a user's .htaccess file, or if httpd.conf has certain misconfigurations, aka Optionsbleed. This affects the Apache HTTP Server through 2.2.34 and 2.4.x through 2.4.27. The attacker sends an unauthenticated OPTIONS HTTP request when attempting to read secret data. This is a use-after-free issue and thus secret data is not always sent, and the specific data depends on many factors including configuration. Exploitation with .htaccess can be blocked with a patch to the ap_limit_section function in server/core.c. | |||||
