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:/&#x • CWE-20: Improper Input Validation CWE-226: Sensitive Information in Resource Not Removed Before Reuse •
CVSS: 6.5EPSS: 0%CPEs: 324EXPL: 0CVE-2019-11135 – hw: TSX Transaction Asynchronous Abort (TAA)
https://notcve.org/view.php?id=CVE-2019-11135
TSX Asynchronous Abort condition on some CPUs utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access. Una condición de tipo TSX Asynchronous Abort en algunas CPU que utilizan ejecución especulativa puede habilitar a un usuario autenticado para permitir potencialmente una divulgación de información por medio de un canal lateral con acceso local. A flaw was found in the way Intel CPUs handle speculative execution of instructions when the TSX Asynchronous Abort (TAA) error occurs. A local authenticated attacker with the ability to monitor execution times could infer the TSX memory state by comparing abort execution times. This could allow information disclosure via this observed side-channel for any TSX transaction being executed while an attacker is able to observe abort timing. Intel's Transactional Synchronisation Extensions (TSX) are set of instructions which enable transactional memory support to improve performance of the multi-threaded applications, in the lock-protected critical sections. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00045.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00046.html http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00042.html http://packetstormsecurity.com/files/155375/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/12/10/3 http://www.openwall.com/lists/oss-security/2019/12/10/4 http://www.openwall.com/lists/oss-security/2019/12 • CWE-203: Observable Discrepancy •
CVSS: 7.3EPSS: 0%CPEs: 3EXPL: 2CVE-2019-14866 – cpio: improper input validation when writing tar header fields leads to unexpected tar generation
https://notcve.org/view.php?id=CVE-2019-14866
In all versions of cpio before 2.13 does not properly validate input files when generating TAR archives. When cpio is used to create TAR archives from paths an attacker can write to, the resulting archive may contain files with permissions the attacker did not have or in paths he did not have access to. Extracting those archives from a high-privilege user without carefully reviewing them may lead to the compromise of the system. En todas las versiones de cpio anteriores a la versión 2.13, no comprueba apropiadamente los archivos de entrada cuando se generan archivos TAR. Cuando cpio es usado para crear archivos TAR desde rutas en las que un atacante puede escribir, el archivo resultante puede contener archivos con permisos que el atacante no tenía o en rutas a las que no tenía acceso. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14866 https://lists.debian.org/debian-lts-announce/2023/06/msg00007.html https://lists.gnu.org/archive/html/bug-cpio/2019-08/msg00003.html https://lists.gnu.org/archive/html/bug-cpio/2019-11/msg00000.html https://access.redhat.com/security/cve/CVE-2019-14866 https://bugzilla.redhat.com/show_bug.cgi?id=1765511 • CWE-20: Improper Input Validation •

A vulnerability was found in Linux Kernel, where a Heap Overflow was found in mwifiex_set_wmm_params() function of Marvell Wifi Driver. Se encontró una vulnerabilidad en Linux Kernel, donde se encontró un desbordamiento de pila en la función mwifiex_set_wmm_params () del controlador Marvell Wifi. A vulnerability found in the Linux kernel's WMM implementation for Marvell WiFi-based hardware (mwifiex) could lead to a denial of service or allow arbitrary code execution. For this flaw to be executed, the attacker must be both local and privileged.

https://notcve.org/view.php?id=CVE-2019-14287
In Sudo before 1.8.28, an attacker with access to a Runas ALL sudoer account can bypass certain policy blacklists and session PAM modules, and can cause incorrect logging, by invoking sudo with a crafted user ID. For example, this allows bypass of !root configuration, and USER= logging, for a "sudo -u \#$((0xffffffff))" command. En Sudo anteriores a 1.8.28, un atacante con acceso a una cuenta Runas ALL sudoer puede omitir ciertas listas negras de políticas y módulos PAM de sesión, y puede causar un registro incorrecto, mediante la invocación sudo con un ID de usuario creado. Por ejemplo, esto permite la omisión de la configuración root y el registro USER= para un comando "sudo -u \#$((0xffffffff))". • https://www.exploit-db.com/exploits/47502 https://github.com/n0w4n/CVE-2019-14287 https://github.com/shallvhack/Sudo-Security-Bypass-CVE-2019-14287 https://github.com/CMNatic/Dockerized-CVE-2019-14287 https://github.com/axax002/sudo-vulnerability-CVE-2019-14287 https://github.com/N3rdyN3xus/CVE-2019-14287 https://github.com/DewmiApsara/CVE-2019-14287 https://github.com/MariliaMeira/CVE-2019-14287 https://github.com/edsonjt81/CVE-2019-14287- https://github.com/SachinthaDeSilva-cmd& • CWE-267: Privilege Defined With Unsafe Actions CWE-755: Improper Handling of Exceptional Conditions •
