CVSS: 7.5EPSS: 1%CPEs: 6EXPL: 0CVE-2018-5734 – A malformed request can trigger an assertion failure in badcache.c
https://notcve.org/view.php?id=CVE-2018-5734
While handling a particular type of malformed packet BIND erroneously selects a SERVFAIL rcode instead of a FORMERR rcode. If the receiving view has the SERVFAIL cache feature enabled, this can trigger an assertion failure in badcache.c when the request doesn't contain all of the expected information. Affects BIND 9.10.5-S1 to 9.10.5-S4, 9.10.6-S1, 9.10.6-S2. Al gestionar un tipo concreto de paquete mal formado, BIND selecciona erróneamente un rcode SERVFAIL en lugar de un rcode FORMERR. Si la vista que se está recibiendo tiene la característica de caché SERVFAIL habilitada, esto puede desencadenar un fallo de aserción en badcache.c cuando la petición no contiene toda la información esperada. • http://www.securityfocus.com/bid/103189 http://www.securitytracker.com/id/1040438 https://kb.isc.org/docs/aa-01562 https://security.netapp.com/advisory/ntap-20180926-0005 • CWE-617: Reachable Assertion •

CVSS: 5.9EPSS: 0%CPEs: 1095EXPL: 0CVE-2018-3693 – Kernel: speculative bounds check bypass store
https://notcve.org/view.php?id=CVE-2018-3693
Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a speculative buffer overflow and side-channel analysis. Los sistemas con microprocesadores que emplean la ejecución especulativa y la predicción de ramas podría permitir la divulgación no autorizada de información a un atacante con acceso de usuario local mediante un desbordamiento de búfer especulativo y el análisis de canal lateral. An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions past bounds check. The flaw relies on the presence of a precisely-defined instruction sequence in the privileged code and the fact that memory writes occur to an address which depends on the untrusted value. Such writes cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). • https://access.redhat.com/errata/RHSA-2018:2384 https://access.redhat.com/errata/RHSA-2018:2390 https://access.redhat.com/errata/RHSA-2018:2395 https://access.redhat.com/errata/RHSA-2019:1946 https://access.redhat.com/errata/RHSA-2020:0174 https://cdrdv2.intel.com/v1/dl/getContent/685359 https://help.ecostruxureit.com/display/public/UADCE725/Security+fixes+in+StruxureWare+Data+Center+Expert+v7.6.0 https://security.netapp.com/advisory/ntap-20180823-0001 https://www.oracle.com/s • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 7.5EPSS: 2%CPEs: 9EXPL: 0CVE-2016-9778 – An error handling certain queries using the nxdomain-redirect feature could cause a REQUIRE assertion failure in db.c
https://notcve.org/view.php?id=CVE-2016-9778
An error in handling certain queries can cause an assertion failure when a server is using the nxdomain-redirect feature to cover a zone for which it is also providing authoritative service. A vulnerable server could be intentionally stopped by an attacker if it was using a configuration that met the criteria for the vulnerability and if the attacker could cause it to accept a query that possessed the required attributes. Please note: This vulnerability affects the "nxdomain-redirect" feature, which is one of two methods of handling NXDOMAIN redirection, and is only available in certain versions of BIND. Redirection using zones of type "redirect" is not affected by this vulnerability. Affects BIND 9.9.8-S1 -> 9.9.8-S3, 9.9.9-S1 -> 9.9.9-S6, 9.11.0-9.11.0-P1. • http://www.securityfocus.com/bid/95388 http://www.securitytracker.com/id/1037582 https://kb.isc.org/article/AA-01442 https://security.gentoo.org/glsa/201708-01 https://security.netapp.com/advisory/ntap-20180926-0005 • CWE-388: 7PK - Errors •
