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 •
CVSS: 7.5EPSS: 5%CPEs: 28EXPL: 1CVE-2017-3143 – An error in TSIG authentication can permit unauthorized dynamic updates
https://notcve.org/view.php?id=CVE-2017-3143
An attacker who is able to send and receive messages to an authoritative DNS server and who has knowledge of a valid TSIG key name for the zone and service being targeted may be able to manipulate BIND into accepting an unauthorized dynamic update. Affects BIND 9.4.0->9.8.8, 9.9.0->9.9.10-P1, 9.10.0->9.10.5-P1, 9.11.0->9.11.1-P1, 9.9.3-S1->9.9.10-S2, 9.10.5-S1->9.10.5-S2. Un atacante que pueda enviar y recibir mensajes a un servidor DNS autoritativo y que conozca un nombre de clave TSIG válido para la zona y el servicio objetivos podría ser capaz de manipular BIND para que acepte una actualización dinámica no autorizada. Afecta a BIND desde la versión 9.4.0 hasta la versión 9.8.8, desde la versión 9.9.0 hasta la versión 9.9.10-P1, desde la versión 9.10.0 hasta la versión 9.10.5-P1, desde la versión 9.11.0 hasta la versión 9.11.1-P1, desde la versión 9.9.3-S1 hasta la versión 9.9.10-S2 y desde la versión 9.10.5-S1 hasta la versión 9.10.5-S2. A flaw was found in the way BIND handled TSIG authentication for dynamic updates. • https://github.com/saaph/CVE-2017-3143 http://www.securityfocus.com/bid/99337 http://www.securitytracker.com/id/1038809 https://access.redhat.com/errata/RHSA-2017:1679 https://access.redhat.com/errata/RHSA-2017:1680 https://h20566.www2.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbux03772en_us https://kb.isc.org/docs/aa-01503 https://security.netapp.com/advisory/ntap-20190830-0003 https://www.debian.org/security/2017/dsa-3904 https://access.redhat • CWE-287: Improper Authentication •

https://notcve.org/view.php?id=CVE-2017-3142
An attacker who is able to send and receive messages to an authoritative DNS server and who has knowledge of a valid TSIG key name may be able to circumvent TSIG authentication of AXFR requests via a carefully constructed request packet. A server that relies solely on TSIG keys for protection with no other ACL protection could be manipulated into: providing an AXFR of a zone to an unauthorized recipient or accepting bogus NOTIFY packets. Affects BIND 9.4.0->9.8.8, 9.9.0->9.9.10-P1, 9.10.0->9.10.5-P1, 9.11.0->9.11.1-P1, 9.9.3-S1->9.9.10-S2, 9.10.5-S1->9.10.5-S2. Un atacante que pueda enviar y recibir mensajes a un servidor DNS autoritativo y que conozca un nombre de clave TSIG válido podría ser capaz de omitir la autenticación TSIG de las peticiones AXFE mediante un paquete de petición cuidadosamente construido. Un servidor que solo depende de las claves TSIG para protegerse sin ningún otro mecanismo de protección de listas de control de acceso podría manipularse para: proporcionar el AXFR de una zona a un destinatario no autorizado o aceptar paquetes NOTIFY falsos. • http://www.securityfocus.com/bid/99339 http://www.securitytracker.com/id/1038809 https://access.redhat.com/errata/RHSA-2017:1679 https://access.redhat.com/errata/RHSA-2017:1680 https://h20566.www2.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbux03772en_us https://kb.isc.org/docs/aa-01504 https://security.netapp.com/advisory/ntap-20190830-0003 https://www.debian.org/security/2017/dsa-3904 https://access.redhat.com/security/cve/CVE-2017-3142 https:/ • CWE-20: Improper Input Validation CWE-287: Improper Authentication •
