CVE-2016-3699 – kernel: ACPI table override allowed when securelevel is enabled
https://notcve.org/view.php?id=CVE-2016-3699
The Linux kernel, as used in Red Hat Enterprise Linux 7.2 and Red Hat Enterprise MRG 2 and when booted with UEFI Secure Boot enabled, allows local users to bypass intended Secure Boot restrictions and execute untrusted code by appending ACPI tables to the initrd. El kernel de Linux, tal como se utiliza en Red Hat Enterprise Linux 7.2 y Red Hat Enterprise MRG 2 y cuando se arranca con UEFI Secure Boot habilitado, permite a usuarios locales eludir las restricciones destinadas a Secure Boot y ejecutar código no confiable añadiendo tablas ACPI para el initrd. • http://rhn.redhat.com/errata/RHSA-2016-2574.html http://rhn.redhat.com/errata/RHSA-2016-2584.html http://www.openwall.com/lists/oss-security/2016/09/22/4 http://www.securityfocus.com/bid/93114 https://bugzilla.redhat.com/show_bug.cgi?id=1329653 https://github.com/mjg59/linux/commit/a4a5ed2835e8ea042868b7401dced3f517cafa76 https://access.redhat.com/security/cve/CVE-2016-3699 • CWE-264: Permissions, Privileges, and Access Controls CWE-358: Improperly Implemented Security Check for Standard •

CVE-2016-2776 – ISC BIND 9 - Denial of Service
https://notcve.org/view.php?id=CVE-2016-2776
buffer.c in named in ISC BIND 9 before 9.9.9-P3, 9.10.x before 9.10.4-P3, and 9.11.x before 9.11.0rc3 does not properly construct responses, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a crafted query. buffer.c en named en ISC BIND 9 en versiones anteriores a 9.9.9-P3, 9.10.x en versiones anteriores a 9.10.4-P3 y 9.11.x en versiones anteriores a 9.11.0rc3 no construye respuestas adecuadamente, lo que permite a atacantes remotos provocar una denegación de servicio (fallo de aserción y salida de demonio) a través de una consulta manipulada. A denial of service flaw was found in the way BIND constructed a response to a query that met certain criteria. A remote attacker could use this flaw to make named exit unexpectedly with an assertion failure via a specially crafted DNS request packet. A defect in the rendering of messages into packets can cause named to exit with an assertion failure in buffer.c while constructing a response to a query that meets certain criteria. This assertion can be triggered even if the apparent source address isnt allowed to make queries. • https://www.exploit-db.com/exploits/40453 https://github.com/infobyte/CVE-2016-2776 http://rhn.redhat.com/errata/RHSA-2016-1944.html http://rhn.redhat.com/errata/RHSA-2016-1945.html http://rhn.redhat.com/errata/RHSA-2016-2099.html http://www.oracle.com/technetwork/topics/security/bulletinoct2016-3090566.html http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2016-3090545.html http://www.oracle.com/technetwork/topics/security/ovmbulletinoct2016-3090547.html http://www.securityf • CWE-20: Improper Input Validation CWE-617: Reachable Assertion •
CVE-2016-2179 – openssl: DTLS memory exhaustion DoS when messages are not removed from fragment buffer
https://notcve.org/view.php?id=CVE-2016-2179
The DTLS implementation in OpenSSL before 1.1.0 does not properly restrict the lifetime of queue entries associated with unused out-of-order messages, which allows remote attackers to cause a denial of service (memory consumption) by maintaining many crafted DTLS sessions simultaneously, related to d1_lib.c, statem_dtls.c, statem_lib.c, and statem_srvr.c. La implementación DTLS en OpenSSL en versiones anteriores a 1.1.0 no restringe adecuadamente la vida útil de entradas de cola asociadas con mensajes fuera de servicio no usados, lo que permite a atacantes remotos provocar una denegación de servicio (consumo de memoria) manteniendo muchas sesiones DTLS manipuladas simultáneamente, relacionado con d1_lib.c, statem_dtls.c, statem_lib.c y statem_srvr.c. It was discovered that the Datagram TLS (DTLS) implementation could fail to release memory in certain cases. A malicious DTLS client could cause a DTLS server using OpenSSL to consume an excessive amount of memory and, possibly, exit unexpectedly after exhausting all available memory. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://rhn.redhat.com/errata/RHSA-2016-1940.html http://www-01.ibm.com/support/docview.wss?uid=swg21995039 http://www.oracle.com/technetwork/security-advisory/cpuapr2018-3678067.html http://www.oracle.com/technetwork/security-advisory/cpujan2018-3236628.html http://www.oracle.com/technetwork/security-advisory/cpujul2017-3236622.html http://www.oracle.com/technetwork/security-advisory/cpuoct2016-2881722.html http://www.oracle.com/technetwork& • CWE-399: Resource Management Errors CWE-772: Missing Release of Resource after Effective Lifetime •
CVE-2016-2182 – openssl: Out-of-bounds write caused by unchecked errors in BN_bn2dec()
https://notcve.org/view.php?id=CVE-2016-2182
The BN_bn2dec function in crypto/bn/bn_print.c in OpenSSL before 1.1.0 does not properly validate division results, which allows remote attackers to cause a denial of service (out-of-bounds write and application crash) or possibly have unspecified other impact via unknown vectors. La función BN_bn2dec en crypto/bn/bn_print.c en OpenSSL en versiones anteriores a 1.1.0 no valida adecuadamente resultados de la división, lo que permite a atacantes remotos provocar una denegación de servicio (escritura fuera de límites y caída de la aplicación) o tener otro posible impacto no especificado a través de vectores desconocidos. An out of bounds write flaw was discovered in the OpenSSL BN_bn2dec() function. An attacker able to make an application using OpenSSL to process a large BIGNUM could cause the application to crash or, possibly, execute arbitrary code. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00011.h • CWE-391: Unchecked Error Condition CWE-787: Out-of-bounds Write •
