CVSS: 9.1EPSS: 46%CPEs: 34EXPL: 0CVE-2017-9788 – httpd: Uninitialized memory reflection in mod_auth_digest
https://notcve.org/view.php?id=CVE-2017-9788
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. En Apache httpd, en versiones anteriores a la 2.2.34 y en versiones 2.4.x anteriores a la 2.4.27, el valor placeholder en cabeceras [Proxy-]Authorization del tipo 'Digest' no se inicializó o reinició antes de o entre las asignaciones sucesivas key=value por mod_auth_digest. Proporcionar una clave inicial sin asignación "=" podría reflejar el valor obsoleto de la memoria agrupada no inicializada utilizada por la petición anterior. Esto podría dar lugar al filtrado de información potencialmente confidencial y, en otros casos, a un fallo de segmentación que daría como resultado una denegación de servicio (DoS) It was discovered that the httpd's mod_auth_digest module did not properly initialize memory before using it when processing certain headers related to digest authentication. • http://www.debian.org/security/2017/dsa-3913 http://www.oracle.com/technetwork/security-advisory/cpuoct2017-3236626.html http://www.securityfocus.com/bid/99569 http://www.securitytracker.com/id/1038906 https://access.redhat.com/errata/RHSA-2017:2478 https://access.redhat.com/errata/RHSA-2017:2479 https://access.redhat.com/errata/RHSA-2017:2483 https://access.redhat.com/errata/RHSA-2017:2708 https://access.redhat.com/errata/RHSA-2017:2709 https://access.redhat.com/errata/RHS • CWE-20: Improper Input Validation CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-456: Missing Initialization of a Variable •

https://notcve.org/view.php?id=CVE-2017-7659
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. Una petición HTTP/2 construida de manera maliciosa podría causar que mod_http2 en el Servidor HTTP de Apache versiones 2.4.24, 2.4.25, desreferencie al puntero NULL y bloquee el procesamiento del servidor. A NULL pointer dereference flaw was found in the mod_http2 module of httpd. A remote attacker could use this flaw to cause httpd child process to crash via a specially crafted HTTP/2 request. • http://www.debian.org/security/2017/dsa-3896 http://www.securityfocus.com/bid/99132 http://www.securitytracker.com/id/1038711 https://access.redhat.com/errata/RHSA-2017:2483 https://lists.apache.org/thread.html/1d0b746bbaa3a64890fcdab59ee9050aaa633b7143e7d412374e5a9a%40%3Cannounce.httpd.apache.org%3E https://lists.apache.org/thread.html/56c2e7cc9deb1c12a843d0dc251ea7fd3e7e80293cde02fcd65286ba%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org/thread.html/84a3714f0878781f6ed84473d1a503d2cc382277e100450209231830%40%3Ccvs.httpd.apache.org%3E • CWE-476: NULL Pointer Dereference •

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. En Apache httpd, en versiones 2.2.x anteriores a la 2.2.33 y versiones 2.4.x anteriores a la 2.4.26, mod_ssl podría desreferenciar un puntero NULL cuando los módulos de terceros llaman a ap_hook_process_connection() durante una petición HTTP a un puerto HTPS. A NULL pointer dereference flaw was found in the httpd's mod_ssl module. A remote attacker could use this flaw to cause an httpd child process to crash if another module used by httpd called a certain API function during the processing of an HTTPS request. • http://www.debian.org/security/2017/dsa-3896 http://www.oracle.com/technetwork/security-advisory/cpuoct2017-3236626.html http://www.securityfocus.com/bid/99134 http://www.securitytracker.com/id/1038711 https://access.redhat.com/errata/RHSA-2017:2478 https://access.redhat.com/errata/RHSA-2017:2479 https://access.redhat.com/errata/RHSA-2017:2483 https://access.redhat.com/errata/RHSA-2017:3193 https://access.redhat.com/errata/RHSA-2017:3194 https://access.redhat.com/errata/RHS • CWE-476: NULL Pointer Dereference •
CVSS: 7.5EPSS: 27%CPEs: 39EXPL: 0CVE-2017-7668 – httpd: ap_find_token() buffer overread
https://notcve.org/view.php?id=CVE-2017-7668
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. Los cambios en el análisis sintáctico estricto de HTTP añadidos en las versiones 2.2.32 y 2.4.24 de Apache httpd introdujeron un error en el análisis de listas de tokens. Esto permite que ap_find_token() busque más allá del final de la cadena de entrada. Un atacante puede conseguir causar un fallo de segmentación o forzar a que ap_find_token() devuelva un valor incorrecto mediante la manipulación de una secuencia de cabeceras de peticiones con fines maliciosos. • http://www.debian.org/security/2017/dsa-3896 http://www.oracle.com/technetwork/security-advisory/cpuoct2017-3236626.html http://www.securityfocus.com/bid/99137 http://www.securitytracker.com/id/1038711 https://access.redhat.com/errata/RHSA-2017:2479 https://access.redhat.com/errata/RHSA-2017:2483 https://access.redhat.com/errata/RHSA-2017:3193 https://access.redhat.com/errata/RHSA-2017:3194 https://lists.apache.org/thread.html/55a068b6a5eec0b3198ae7d96a7cb412352d0ffa7716612c5af3745b%40%3Cdev.httpd. • CWE-122: Heap-based Buffer Overflow CWE-125: Out-of-bounds Read CWE-126: Buffer Over-read •

https://notcve.org/view.php?id=CVE-2017-3167
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. En Apache httpd, en versiones 2.2.x anteriores a la 2.2.33 y versiones 2.4.x anteriores a la 2.4.26, el uso de ap_get_basic_auth_pw() por parte de módulos de terceros fuera de la fase de autenticación puede dar lugar a que se omitan requisitos de autenticación.. It was discovered that the use of httpd's ap_get_basic_auth_pw() API function outside of the authentication phase could lead to authentication bypass. A remote attacker could possibly use this flaw to bypass required authentication if the API was used incorrectly by one of the modules used by httpd. • http://www.debian.org/security/2017/dsa-3896 http://www.oracle.com/technetwork/security-advisory/cpuoct2017-3236626.html http://www.securityfocus.com/bid/99135 http://www.securitytracker.com/id/1038711 https://access.redhat.com/errata/RHSA-2017:2478 https://access.redhat.com/errata/RHSA-2017:2479 https://access.redhat.com/errata/RHSA-2017:2483 https://access.redhat.com/errata/RHSA-2017:3193 https://access.redhat.com/errata/RHSA-2017:3194 https://access.redhat.com/errata/RHS • CWE-287: Improper Authentication •
