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 •
CVE-2018-14468 – tcpdump: Buffer over-read in mfr_print() function in print-fr.c
https://notcve.org/view.php?id=CVE-2018-14468
The FRF.16 parser in tcpdump before 4.9.3 has a buffer over-read in print-fr.c:mfr_print(). El analizador FRF.16 en tcpdump versiones anteriores a 4.9.3, presenta una lectura excesiva del búfer en print-fr.c:mfr_print(). An out-of-bounds read vulnerability was discovered in tcpdump while printing FRF.16 packets captured in a pcap file or coming from the network. A remote attacker may abuse this flaw by sending specially crafted packets that, when printed, would trigger the flaw and crash the application. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00050.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00053.html http://seclists.org/fulldisclosure/2019/Dec/26 https://github.com/the-tcpdump-group/tcpdump/blob/tcpdump-4.9/CHANGES https://github.com/the-tcpdump-group/tcpdump/commit/aa3e54f594385ce7e1e319b0c84999e51192578b https://lists.debian.org/debian-lts-announce/2019/10/msg00015.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/ • CWE-125: Out-of-bounds Read •
