|---|---|---|---|---|---|
| CVE-2017-9798 | 2 Apache, Debian | 2 Http Server, Debian Linux | 2025-04-20 | 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. | |||||
| CVE-2017-9788 | 6 Apache, Apple, Debian and 3 more | 16 Http Server, Mac Os X, Debian Linux and 13 more | 2025-04-20 | 6.4 MEDIUM | 9.1 CRITICAL |
| In Apache httpd before 2.2.34 and 2.4.x before 2.4.27, the value placeholder in [Proxy-]Authorization headers of type 'Digest' was not initialized or reset before or between successive key=value assignments by mod_auth_digest. Providing an initial key with no '=' assignment could reflect the stale value of uninitialized pool memory used by the prior request, leading to leakage of potentially confidential information, and a segfault in other cases resulting in denial of service. | |||||
| CVE-2016-2161 | 1 Apache | 1 Http Server | 2025-04-20 | 5.0 MEDIUM | 7.5 HIGH |
| In Apache HTTP Server versions 2.4.0 to 2.4.23, malicious input to mod_auth_digest can cause the server to crash, and each instance continues to crash even for subsequently valid requests. | |||||
| CVE-2017-3167 | 6 Apache, Apple, Debian and 3 more | 15 Http Server, Mac Os X, Debian Linux and 12 more | 2025-04-20 | 7.5 HIGH | 9.8 CRITICAL |
| In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, use of the ap_get_basic_auth_pw() by third-party modules outside of the authentication phase may lead to authentication requirements being bypassed. | |||||
| CVE-2017-9789 | 1 Apache | 1 Http Server | 2025-04-20 | 5.0 MEDIUM | 7.5 HIGH |
| When under stress, closing many connections, the HTTP/2 handling code in Apache httpd 2.4.26 would sometimes access memory after it has been freed, resulting in potentially erratic behaviour. | |||||
| CVE-2016-0736 | 1 Apache | 1 Http Server | 2025-04-20 | 5.0 MEDIUM | 7.5 HIGH |
| In Apache HTTP Server versions 2.4.0 to 2.4.23, mod_session_crypto was encrypting its data/cookie using the configured ciphers with possibly either CBC or ECB modes of operation (AES256-CBC by default), hence no selectable or builtin authenticated encryption. This made it vulnerable to padding oracle attacks, particularly with CBC. | |||||
| CVE-2017-7659 | 1 Apache | 1 Http Server | 2025-04-20 | 5.0 MEDIUM | 7.5 HIGH |
| A maliciously constructed HTTP/2 request could cause mod_http2 in Apache HTTP Server 2.4.24, 2.4.25 to dereference a NULL pointer and crash the server process. | |||||
| CVE-2014-0118 | 3 Apache, Debian, Redhat | 4 Http Server, Debian Linux, Enterprise Linux and 1 more | 2025-04-12 | 4.3 MEDIUM | N/A |
| The deflate_in_filter function in mod_deflate.c in the mod_deflate module in the Apache HTTP Server before 2.4.10, when request body decompression is enabled, allows remote attackers to cause a denial of service (resource consumption) via crafted request data that decompresses to a much larger size. | |||||
| CVE-2014-0226 | 4 Apache, Debian, Oracle and 1 more | 7 Http Server, Debian Linux, Enterprise Manager Ops Center and 4 more | 2025-04-12 | 6.8 MEDIUM | N/A |
| Race condition in the mod_status module in the Apache HTTP Server before 2.4.10 allows remote attackers to cause a denial of service (heap-based buffer overflow), or possibly obtain sensitive credential information or execute arbitrary code, via a crafted request that triggers improper scoreboard handling within the status_handler function in modules/generators/mod_status.c and the lua_ap_scoreboard_worker function in modules/lua/lua_request.c. | |||||
| CVE-2014-3581 | 4 Apache, Canonical, Oracle and 1 more | 9 Http Server, Ubuntu Linux, Enterprise Manager Ops Center and 6 more | 2025-04-12 | 5.0 MEDIUM | N/A |
| The cache_merge_headers_out function in modules/cache/cache_util.c in the mod_cache module in the Apache HTTP Server before 2.4.11 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an empty HTTP Content-Type header. | |||||
| CVE-2016-1546 | 1 Apache | 1 Http Server | 2025-04-12 | 4.3 MEDIUM | 5.9 MEDIUM |
| The Apache HTTP Server 2.4.17 and 2.4.18, when mod_http2 is enabled, does not limit the number of simultaneous stream workers for a single HTTP/2 connection, which allows remote attackers to cause a denial of service (stream-processing outage) via modified flow-control windows. | |||||
| CVE-2014-3583 | 3 Apache, Apple, Canonical | 4 Http Server, Mac Os X, Os X Server and 1 more | 2025-04-12 | 5.0 MEDIUM | N/A |
| The handle_headers function in mod_proxy_fcgi.c in the mod_proxy_fcgi module in the Apache HTTP Server 2.4.10 allows remote FastCGI servers to cause a denial of service (buffer over-read and daemon crash) via long response headers. | |||||
| CVE-2016-4979 | 1 Apache | 1 Http Server | 2025-04-12 | 5.0 MEDIUM | 7.5 HIGH |
| The Apache HTTP Server 2.4.18 through 2.4.20, when mod_http2 and mod_ssl are enabled, does not properly recognize the "SSLVerifyClient require" directive for HTTP/2 request authorization, which allows remote attackers to bypass intended access restrictions by leveraging the ability to send multiple requests over a single connection and aborting a renegotiation. | |||||
| CVE-2014-0098 | 3 Apache, Canonical, Oracle | 4 Http Server, Ubuntu Linux, Http Server and 1 more | 2025-04-12 | 5.0 MEDIUM | N/A |
| The log_cookie function in mod_log_config.c in the mod_log_config module in the Apache HTTP Server before 2.4.8 allows remote attackers to cause a denial of service (segmentation fault and daemon crash) via a crafted cookie that is not properly handled during truncation. | |||||

| The dav_xml_get_cdata function in main/util.c in the mod_dav module in the Apache HTTP Server before 2.4.8 does not properly remove whitespace characters from CDATA sections, which allows remote attackers to cause a denial of service (daemon crash) via a crafted DAV WRITE request. | |||||
| CVE-2014-0231 | 1 Apache | 1 Http Server | 2025-04-12 | 5.0 MEDIUM | N/A |
| The mod_cgid module in the Apache HTTP Server before 2.4.10 does not have a timeout mechanism, which allows remote attackers to cause a denial of service (process hang) via a request to a CGI script that does not read from its stdin file descriptor. | |||||
| CVE-2015-0253 | 3 Apache, Apple, Oracle | 5 Http Server, Mac Os X, Mac Os X Server and 2 more | 2025-04-12 | 5.0 MEDIUM | N/A |
| The read_request_line function in server/protocol.c in the Apache HTTP Server 2.4.12 does not initialize the protocol structure member, which allows remote attackers to cause a denial of service (NULL pointer dereference and process crash) by sending a request that lacks a method to an installation that enables the INCLUDES filter and has an ErrorDocument 400 directive specifying a local URI. | |||||
| CVE-2013-4352 | 1 Apache | 1 Http Server | 2025-04-12 | 4.3 MEDIUM | N/A |
| The cache_invalidate function in modules/cache/cache_storage.c in the mod_cache module in the Apache HTTP Server 2.4.6, when a caching forward proxy is enabled, allows remote HTTP servers to cause a denial of service (NULL pointer dereference and daemon crash) via vectors that trigger a missing hostname value. | |||||
| CVE-2016-5387 | 8 Apache, Canonical, Debian and 5 more | 21 Http Server, Ubuntu Linux, Debian Linux and 18 more | 2025-04-12 | 6.8 MEDIUM | 8.1 HIGH |
| The Apache HTTP Server through 2.4.23 follows RFC 3875 section 4.1.18 and therefore does not protect applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect an application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an "httpoxy" issue. NOTE: the vendor states "This mitigation has been assigned the identifier CVE-2016-5387"; in other words, this is not a CVE ID for a vulnerability. | |||||
| CVE-2014-3523 | 2 Apache, Microsoft | 2 Http Server, Windows | 2025-04-12 | 5.0 MEDIUM | N/A |
| Memory leak in the winnt_accept function in server/mpm/winnt/child.c in the WinNT MPM in the Apache HTTP Server 2.4.x before 2.4.10 on Windows, when the default AcceptFilter is enabled, allows remote attackers to cause a denial of service (memory consumption) via crafted requests. | |||||
