https://notcve.org/view.php?id=CVE-2018-1068
A flaw was found in the Linux 4.x kernel's implementation of 32-bit syscall interface for bridging. This allowed a privileged user to arbitrarily write to a limited range of kernel memory. Se ha encontrado un error en la implementación de la interfaz syscall de 32 bits para puentes de red (bridging) en el kernel de las versiones 4.x de Linux. Esto permitía que un usuario privilegiado escribiese de forma arbitraria en un rango limitado de memoria del kernel.

Memory safety bugs were reported in Firefox ESR 52.6. These bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Firefox ESR < 52.7 and Thunderbird < 52.7. Se han informado de errores de seguridad de memoria en Firefox ESR 52.6. Estos errores mostraron evidencias de corrupción de memoria y se cree que, con el esfuerzo necesario, se podrían explotar para ejecutar código arbitrario. • http://www.securityfocus.com/bid/103384 http://www.securitytracker.com/id/1040514 https://access.redhat.com/errata/RHSA-2018:0526 https://access.redhat.com/errata/RHSA-2018:0527 https://access.redhat.com/errata/RHSA-2018:0647 https://access.redhat.com/errata/RHSA-2018:0648 https://bugzilla.mozilla.org/buglist.cgi?bug_id=1261175%2C1348955 https://lists.debian.org/debian-lts-announce/2018/03/msg00010.html https://lists.debian.org/debian-lts-announce/2018/03/msg00029.html https:& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

https://notcve.org/view.php?id=CVE-2018-7858
Quick Emulator (aka QEMU), when built with the Cirrus CLGD 54xx VGA Emulator support, allows local guest OS privileged users to cause a denial of service (out-of-bounds access and QEMU process crash) by leveraging incorrect region calculation when updating VGA display. Quick Emulator (también conocido como QEMU), cuando se integra con soporte para Cirrus CLGD 54xx VGA Emulator, permite que usuarios privilegiados locales, invitados del sistema operativo, provoquen una denegación de servicio (acceso fuera de límites y cierre inesperado del proceso QEMU) aprovechando los cálculos de región incorrectos al actualizar la pantalla VGA. • http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00042.html http://www.openwall.com/lists/oss-security/2018/03/09/1 http://www.securityfocus.com/bid/103350 https://access.redhat.com/errata/RHSA-2018:1369 https://access.redhat.com/errata/RHSA-2018:1416 https://access.redhat.com/errata/RHSA-2018:2162 https://bugzilla.redhat.com/show_bug.cgi?id=1553402 https://lists.nongnu.org/archive/html/qemu-devel/2018-03/msg02174.html https://usn.ubuntu.com/3649-1 ht • CWE-125: Out-of-bounds Read •

CVSS: 7.5EPSS: 7%CPEs: 55EXPL: 0CVE-2018-5733 – A malicious client can overflow a reference counter in ISC dhcpd
https://notcve.org/view.php?id=CVE-2018-5733
A malicious client which is allowed to send very large amounts of traffic (billions of packets) to a DHCP server can eventually overflow a 32-bit reference counter, potentially causing dhcpd to crash. Affects ISC DHCP 4.1.0 -> 4.1-ESV-R15, 4.2.0 -> 4.2.8, 4.3.0 -> 4.3.6, 4.4.0. Un cliente malicioso al que se le permite enviar grandes cantidades de tráfico (miles de millones de paquetes) a un servidor DHCP puede terminar desbordando un contador de referencia de 32 bits, provocando el cierre inesperado de dhcpd. Afecta a ISC DHCP desde la versión 4.1.0 hasta la 4.1-ESV-R15, desde la versión 4.2.0 hasta la 4.2.8, desde la versión 4.3.0 hasta la 4.3.6 y a la versión 4.4.0. A denial of service flaw was found in the way dhcpd handled reference counting when processing client requests. • http://www.securityfocus.com/bid/103188 http://www.securitytracker.com/id/1040437 https://access.redhat.com/errata/RHSA-2018:0469 https://access.redhat.com/errata/RHSA-2018:0483 https://kb.isc.org/docs/aa-01567 https://lists.debian.org/debian-lts-announce/2018/03/msg00015.html https://usn.ubuntu.com/3586-1 https://usn.ubuntu.com/3586-2 https://www.debian.org/security/2018/dsa-4133 https://access.redhat.com/security/cve/CVE-2018-5733 https://bugzilla.redhat • CWE-190: Integer Overflow or Wraparound •
