CVE-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 •
CVE-2016-9589 – wildfly: ParseState headerValuesCache can be exploited to fill heap with garbage
https://notcve.org/view.php?id=CVE-2016-9589
Undertow in Red Hat wildfly before version 11.0.0.Beta1 is vulnerable to a resource exhaustion resulting in a denial of service. Undertow keeps a cache of seen HTTP headers in persistent connections. It was found that this cache can easily exploited to fill memory with garbage, up to "max-headers" (default 200) * "max-header-size" (default 1MB) per active TCP connection. Undertow en Red Hat wildfly, en versiones anteriores a la 11.0.0.Beta1, es vulnerable a un agotamiento de recursos, lo cual resulta en una denegación de servicio (DoS). Undertow mantiene una caché de las cabeceras HTTP vistas en conexiones persistentes. • http://rhn.redhat.com/errata/RHSA-2017-0830.html http://rhn.redhat.com/errata/RHSA-2017-0831.html http://rhn.redhat.com/errata/RHSA-2017-0832.html http://rhn.redhat.com/errata/RHSA-2017-0834.html http://rhn.redhat.com/errata/RHSA-2017-0876.html http://www.securityfocus.com/bid/97060 https://access.redhat.com/errata/RHSA-2017:0872 https://access.redhat.com/errata/RHSA-2017:0873 https://access.redhat.com/errata/RHSA-2017:3454 https://access.redhat.com/errata/ • CWE-400: Uncontrolled Resource Consumption •
CVE-2016-8610 – SSL/TLS: Malformed plain-text ALERT packets could cause remote DoS
https://notcve.org/view.php?id=CVE-2016-8610
A denial of service flaw was found in OpenSSL 0.9.8, 1.0.1, 1.0.2 through 1.0.2h, and 1.1.0 in the way the TLS/SSL protocol defined processing of ALERT packets during a connection handshake. A remote attacker could use this flaw to make a TLS/SSL server consume an excessive amount of CPU and fail to accept connections from other clients. Se ha encontrado un fallo de denegación de servicio en OpenSSL en las versiones 0.9.8, 1.0.1, 1.0.2 hasta la 1.0.2h y la 1.1.0 en la forma en la que el protocolo TLS/SSL definió el procesamiento de paquetes ALERT durante una negociación de conexión. Un atacante remoto podría emplear este fallo para hacer que un servidor TLS/SSL consuma una cantidad excesiva de recursos de CPU y fracase a la hora de aceptar conexiones de otros clientes.
