https://notcve.org/view.php?id=CVE-2018-11763
25 Sep 2018 — In Apache HTTP Server 2.4.17 to 2.4.34, by sending continuous, large SETTINGS frames a client can occupy a connection, server thread and CPU time without any connection timeout coming to effect. This affects only HTTP/2 connections. A possible mitigation is to not enable the h2 protocol. En Apache HTTP Server, de la versión 2.4.17 a la 2.4.34, mediante el envío continuo de tramas SETTINGS grandes, un cliente puede ocupar una conexión, hilo del servidor y tiempo de CPU sin que se active ningún agotamiento de... • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00030.html • CWE-20: Improper Input Validation •

CVE-2016-4975 – mod_userdir CRLF injection
https://notcve.org/view.php?id=CVE-2016-4975
14 Aug 2018 — Possible CRLF injection allowing HTTP response splitting attacks for sites which use mod_userdir. This issue was mitigated by changes made in 2.4.25 and 2.2.32 which prohibit CR or LF injection into the "Location" or other outbound header key or value. Fixed in Apache HTTP Server 2.4.25 (Affected 2.4.1-2.4.23). Fixed in Apache HTTP Server 2.2.32 (Affected 2.2.0-2.2.31).

CVE-2018-8011 – mod_md, DoS via Coredumps on specially crafted requests
https://notcve.org/view.php?id=CVE-2018-8011
18 Jul 2018 — By specially crafting HTTP requests, the mod_md challenge handler would dereference a NULL pointer and cause the child process to segfault. This could be used to DoS the server. Fixed in Apache HTTP Server 2.4.34 (Affected 2.4.33). Manipulando especialmente peticiones HTTP, el manipulador challenge mod_md desreferencia un puntero NULL y hace que el proceso hijo entre en segfault. Esto podría emplearse para provocar una denegación de servicio (DoS) en el servidor. • http://www.securitytracker.com/id/1041401 • CWE-476: NULL Pointer Dereference •

CVE-2018-1333 – DoS for HTTP/2 connections by crafted requests
https://notcve.org/view.php?id=CVE-2018-1333
18 Jun 2018 — By specially crafting HTTP/2 requests, workers would be allocated 60 seconds longer than necessary, leading to worker exhaustion and a denial of service. Fixed in Apache HTTP Server 2.4.34 (Affected 2.4.18-2.4.30,2.4.33). Al manipular especialmente las peticiones HTTP/2, los trabajadores se asignarían 60 segundos más de los necesarios, lo que conduce a un agotamiento de los trabajadores y a una denegación de servicio (DoS). Esto se ha solucionado en Apache HTTP Server 2.4.34 (2.4.18 - 2.4.30, 2.4.33 afectad... • http://www.securitytracker.com/id/1041402 • CWE-400: Uncontrolled Resource Consumption •

CVE-2017-15710 – httpd: Out of bounds write in mod_authnz_ldap when using too small Accept-Language values
https://notcve.org/view.php?id=CVE-2017-15710
26 Mar 2018 — In Apache httpd 2.0.23 to 2.0.65, 2.2.0 to 2.2.34, and 2.4.0 to 2.4.29, mod_authnz_ldap, if configured with AuthLDAPCharsetConfig, uses the Accept-Language header value to lookup the right charset encoding when verifying the user's credentials. If the header value is not present in the charset conversion table, a fallback mechanism is used to truncate it to a two characters value to allow a quick retry (for example, 'en-US' is truncated to 'en'). A header value of less than two characters forces an out of b... • http://www.openwall.com/lists/oss-security/2018/03/24/8 • CWE-787: Out-of-bounds Write •

CVE-2018-1283 – httpd: Improper handling of headers in mod_session can allow a remote user to modify session data for CGI applications
https://notcve.org/view.php?id=CVE-2018-1283
26 Mar 2018 — In Apache httpd 2.4.0 to 2.4.29, when mod_session is configured to forward its session data to CGI applications (SessionEnv on, not the default), a remote user may influence their content by using a "Session" header. This comes from the "HTTP_SESSION" variable name used by mod_session to forward its data to CGIs, since the prefix "HTTP_" is also used by the Apache HTTP Server to pass HTTP header fields, per CGI specifications. En Apache httpd, versiones 2.4.0 hasta la 2.4.29, cuando se configura mod_session... • http://www.openwall.com/lists/oss-security/2018/03/24/4 • CWE-20: Improper Input Validation •

CVE-2018-1301 – httpd: Out of bounds access after failure in reading the HTTP request
https://notcve.org/view.php?id=CVE-2018-1301
26 Mar 2018 — A specially crafted request could have crashed the Apache HTTP Server prior to version 2.4.30, due to an out of bound access after a size limit is reached by reading the HTTP header. This vulnerability is considered very hard if not impossible to trigger in non-debug mode (both log and build level), so it is classified as low risk for common server usage.

CVE-2018-1302 – httpd: Use-after-free on HTTP/2 stream shutdown
https://notcve.org/view.php?id=CVE-2018-1302
26 Mar 2018 — When an HTTP/2 stream was destroyed after being handled, the Apache HTTP Server prior to version 2.4.30 could have written a NULL pointer potentially to an already freed memory. The memory pools maintained by the server make this vulnerability hard to trigger in usual configurations, the reporter and the team could not reproduce it outside debug builds, so it is classified as low risk. Cuando un flujo de datos o stream HTTP/2 se destruye después de haber sido manipulado, el servidor Apache HTTP en versiones... • http://www.openwall.com/lists/oss-security/2018/03/24/5 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-476: NULL Pointer Dereference •

CVE-2018-1303 – httpd: Out of bounds read in mod_cache_socache can allow a remote attacker to cause DoS
https://notcve.org/view.php?id=CVE-2018-1303
26 Mar 2018 — A specially crafted HTTP request header could have crashed the Apache HTTP Server prior to version 2.4.30 due to an out of bound read while preparing data to be cached in shared memory. It could be used as a Denial of Service attack against users of mod_cache_socache. The vulnerability is considered as low risk since mod_cache_socache is not widely used, mod_cache_disk is not concerned by this vulnerability.
