CVE-2020-9488 – log4j: improper validation of certificate with host mismatch in SMTP appender
https://notcve.org/view.php?id=CVE-2020-9488
Improper validation of certificate with host mismatch in Apache Log4j SMTP appender. This could allow an SMTPS connection to be intercepted by a man-in-the-middle attack which could leak any log messages sent through that appender. Fixed in Apache Log4j 2.12.3 and 2.13.1 Validación incorrecta del certificado con desajuste de host en el apéndice SMTP de Apache Log4j. Esto podría permitir que una conexión SMTPS fuera interceptada por un ataque de tipo man-in-the-middle que podría filtrar cualquier mensaje de registro enviado a través de ese appender. Corregido en Apache Log4j 2.12.3 y 2.13.1 • https://issues.apache.org/jira/browse/LOG4J2-2819 https://lists.apache.org/thread.html/r0a2699f724156a558afd1abb6c044fb9132caa66dce861b82699722a%40%3Cjira.kafka.apache.org%3E https://lists.apache.org/thread.html/r0df3d7a5acb98c57e64ab9266aa21eeee1d9b399addb96f9cf1cbe05%40%3Cdev.zookeeper.apache.org%3E https://lists.apache.org/thread.html/r1fc73f0e16ec2fa249d3ad39a5194afb9cc5afb4c023dc0bab5a5881%40%3Cissues.hive.apache.org%3E https://lists.apache.org/thread.html/r22a56beb76dd8cf18e24fda9072f1e05990f49d6439662d3782a392f%40%3Cissues.hive.apache.org%3E https://lists.apache.o • CWE-295: Improper Certificate Validation •
CVE-2020-1967 – Segmentation fault in SSL_check_chain
https://notcve.org/view.php?id=CVE-2020-1967
Server or client applications that call the SSL_check_chain() function during or after a TLS 1.3 handshake may crash due to a NULL pointer dereference as a result of incorrect handling of the "signature_algorithms_cert" TLS extension. The crash occurs if an invalid or unrecognised signature algorithm is received from the peer. This could be exploited by a malicious peer in a Denial of Service attack. OpenSSL version 1.1.1d, 1.1.1e, and 1.1.1f are affected by this issue. This issue did not affect OpenSSL versions prior to 1.1.1d. • https://github.com/irsl/CVE-2020-1967 http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00011.html http://packetstormsecurity.com/files/157527/OpenSSL-signature_algorithms_cert-Denial-Of-Service.html http://seclists.org/fulldisclosure/2020/May/5 http://www.openwall.com/lists/oss-security/2020/04/22/2 https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=eb563247aef3e83dda7679c43f9649270462e5b1 https:/ • CWE-476: NULL Pointer Dereference •
CVE-2019-17571 – log4j: deserialization of untrusted data in SocketServer
https://notcve.org/view.php?id=CVE-2019-17571
Included in Log4j 1.2 is a SocketServer class that is vulnerable to deserialization of untrusted data which can be exploited to remotely execute arbitrary code when combined with a deserialization gadget when listening to untrusted network traffic for log data. This affects Log4j versions up to 1.2 up to 1.2.17. Incluido en Log4j versión 1.2 existe una clase SocketServer que es vulnerable a la deserialización de datos no confiables, que pueden ser explotada para ejecutar código arbitrario remotamente cuando se combina con un dispositivo de deserialización al escuchar el tráfico de red no confiable para datos de registro. Esto afecta a Log4j versiones desde 1.2 hasta 1.2.17. A flaw was discovered in Log4j, where a vulnerable SocketServer class may lead to the deserialization of untrusted data. • https://github.com/shadow-horse/CVE-2019-17571 https://github.com/Al1ex/CVE-2019-17571 http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00022.html https://lists.apache.org/thread.html/277b4b5c2b0e06a825ccec565fa65bd671f35a4d58e3e2ec5d0618e1%40%3Cdev.tika.apache.org%3E https://lists.apache.org/thread.html/44491fb9cc19acc901f7cff34acb7376619f15638439416e3e14761c%40%3Cdev.tika.apache.org%3E https://lists.apache.org/thread.html/479471e6debd608c837b9815b76eab24676657d4444fcfd5ef96d6e6%40%3Cdev.tika.apache.org%3E https://lists.apache& • CWE-502: Deserialization of Untrusted Data •
CVE-2018-12207 – hw: Machine Check Error on Page Size Change (IFU)
https://notcve.org/view.php?id=CVE-2018-12207
Improper invalidation for page table updates by a virtual guest operating system for multiple Intel(R) Processors may allow an authenticated user to potentially enable denial of service of the host system via local access. Una invalidación inapropiada de las actualizaciones de la tabla de páginas por parte de un sistema operativo invitado virtual para múltiples procesadores Intel® puede habilitar a un usuario autenticado para permitir potencialmente una denegación de servicio del sistema host por medio de un acceso local. A flaw was found in the way Intel CPUs handle inconsistency between, virtual to physical memory address translations in CPU's local cache and system software's Paging structure entries. A privileged guest user may use this flaw to induce a hardware Machine Check Error on the host processor, resulting in a severe DoS scenario by halting the processor. System software like OS OR Virtual Machine Monitor (VMM) use virtual memory system for storing program instructions and data in memory. Virtual Memory system uses Paging structures like Page Tables and Page Directories to manage system memory. • http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00042.html https://access.redhat.com/errata/RHSA-2019:3916 https://access.redhat.com/errata/RHSA-2019:3936 https://access.redhat.com/errata/RHSA-2019:3941 https://access.redhat.com/errata/RHSA-2020:0026 https://access.redhat.com/errata/RHSA-2020:0028 https://access.redhat.com/errata/RHSA-2020:0204 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/I5WWPW4BSZDDW7VHU427XTVXV7ROOFFW https:/ • CWE-20: Improper Input Validation CWE-226: Sensitive Information in Resource Not Removed Before Reuse •
