xmltok_impl.c in Expat (aka libexpat) before 2.4.5 lacks certain validation of encoding, such as checks for whether a UTF-8 character is valid in a certain context.
CVE-2020-11993 8 Apache, Canonical, Debian and 5 more 16 Http Server, Ubuntu Linux, Debian Linux and 13 more 2025-05-01 7.5 High
Apache HTTP Server versions 2.4.20 to 2.4.43 When trace/debug was enabled for the HTTP/2 module and on certain traffic edge patterns, logging statements were made on the wrong connection, causing concurrent use of memory pools. Configuring the LogLevel of mod_http2 above "info" will mitigate this vulnerability for unpatched servers.
CVE-2021-33193 6 Apache, Debian, Fedoraproject and 3 more 9 Http Server, Debian Linux, Fedora and 6 more 2025-05-01 7.5 High
A crafted method sent through HTTP/2 will bypass validation and be forwarded by mod_proxy, which can lead to request splitting or cache poisoning. This issue affects Apache HTTP Server 2.4.17 to 2.4.48.
CVE-2021-36160 7 Apache, Broadcom, Debian and 4 more 16 Http Server, Brocade Fabric Operating System Firmware, Debian Linux and 13 more 2025-05-01 7.5 High
A carefully crafted request uri-path can cause mod_proxy_uwsgi to read above the allocated memory and crash (DoS). This issue affects Apache HTTP Server versions 2.4.30 to 2.4.48 (inclusive).
CVE-2021-39275 7 Apache, Debian, Fedoraproject and 4 more 14 Http Server, Debian Linux, Fedora and 11 more 2025-05-01 9.8 Critical
ap_escape_quotes() may write beyond the end of a buffer when given malicious input. No included modules pass untrusted data to these functions, but third-party / external modules may. This issue affects Apache HTTP Server 2.4.48 and earlier.
CVE-2021-44790 8 Apache, Apple, Debian and 5 more 20 Http Server, Mac Os X, Macos and 17 more 2025-05-01 9.8 Critical
A carefully crafted request body can cause a buffer overflow in the mod_lua multipart parser (r:parsebody() called from Lua scripts). The Apache httpd team is not aware of an exploit for the vulnerabilty though it might be possible to craft one. This issue affects Apache HTTP Server 2.4.51 and earlier.
CVE-2022-23943 5 Apache, Debian, Fedoraproject and 2 more 8 Http Server, Debian Linux, Fedora and 5 more 2025-05-01 9.8 Critical
Out-of-bounds Write vulnerability in mod_sed of Apache HTTP Server allows an attacker to overwrite heap memory with possibly attacker provided data. This issue affects Apache HTTP Server 2.4 version 2.4.52 and prior versions.
CVE-2022-21716 5 Debian, Fedoraproject, Oracle and 2 more 6 Debian Linux, Fedora, Http Server and 3 more 2025-04-22 7.5 High
Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to 22.2.0, Twisted SSH client and server implement is able to accept an infinite amount of data for the peer's SSH version identifier. This ends up with a buffer using all the available memory. The attach is a simple as `nc -rv localhost 22 < /dev/zero`. A patch is available in version 22.2.0. There are currently no known workarounds.
CVE-2017-7668 6 Apache, Apple, Debian and 3 more 16 Http Server, Mac Os X, Debian Linux and 13 more 2025-04-20 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-2017-3167 6 Apache, Apple, Debian and 3 more 17 Http Server, Mac Os X, Debian Linux and 14 more 2025-04-20 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-2017-9788 6 Apache, Apple, Debian and 3 more 18 Http Server, Mac Os X, Debian Linux and 15 more 2025-04-20 N/A
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-2016-3482 1 Oracle 1 Http Server 2025-04-12 N/A
Unspecified vulnerability in the Oracle HTTP Server component in Oracle Fusion Middleware 11.1.1.9 and 12.1.3.0 allows remote attackers to affect confidentiality via vectors related to SSL/TLS Module.
CVE-2013-6438 4 Apache, Canonical, Oracle and 1 more 6 Http Server, Ubuntu Linux, Http Server and 3 more 2025-04-12 N/A
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-2014-0098 4 Apache, Canonical, Oracle and 1 more 7 Http Server, Ubuntu Linux, Http Server and 4 more 2025-04-12 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.
CVE-2014-8109 4 Apache, Canonical, Fedoraproject and 1 more 4 Http Server, Ubuntu Linux, Fedora and 1 more 2025-04-12 N/A
mod_lua.c in the mod_lua module in the Apache HTTP Server 2.3.x and 2.4.x through 2.4.10 does not support an httpd configuration in which the same Lua authorization provider is used with different arguments within different contexts, which allows remote attackers to bypass intended access restrictions in opportunistic circumstances by leveraging multiple Require directives, as demonstrated by a configuration that specifies authorization for one group to access a certain directory, and authorization for a second group to access a second directory.
CVE-2014-0226 4 Apache, Debian, Oracle and 1 more 9 Http Server, Debian Linux, Enterprise Manager Ops Center and 6 more 2025-04-12 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.
