https://notcve.org/view.php?id=CVE-2020-27827
A flaw was found in multiple versions of OpenvSwitch. Specially crafted LLDP packets can cause memory to be lost when allocating data to handle specific optional TLVs, potentially causing a denial of service. The highest threat from this vulnerability is to system availability. Se encontró un fallo en múltiples versiones de OpenvSwitch. Los paquetes LLDP especialmente diseñados pueden causar que una memoria se pierda cuando se asignan datos para manejar TLV opcionales específicos, potencialmente causando una denegación de servicio. • https://bugzilla.redhat.com/show_bug.cgi?id=1921438 https://cert-portal.siemens.com/productcert/pdf/ssa-941426.pdf https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3T5XHPOGIPWCRRPJUE6P3HVC5PTSD5JS https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JYA4AMJXCNF6UPFG36L2TPPT32C242SP https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SKQWHG2SZJZSGC7PXVDAEJYBN7ESDR7D https://mail.openvswitch.org/pipermail/ovs-dev/2021&# • CWE-400: Uncontrolled Resource Consumption •
CVSS: 9.9EPSS: 0%CPEs: 2EXPL: 0CVE-2020-14316 – kubevirt: VMIs can be used to access host files
https://notcve.org/view.php?id=CVE-2020-14316
A flaw was found in kubevirt 0.29 and earlier. Virtual Machine Instances (VMIs) can be used to gain access to the host's filesystem. Successful exploitation allows an attacker to assume the privileges of the VM process on the host system. In worst-case scenarios an attacker can read and modify any file on the system where the VMI is running. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. • https://bugzilla.redhat.com/show_bug.cgi?id=1848951 https://access.redhat.com/security/cve/CVE-2020-14316 • CWE-284: Improper Access Control •

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 •

https://notcve.org/view.php?id=CVE-2019-14835
A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host. Se encontró un fallo de desbordamiento de búfer, en las versiones desde 2.6.34 hasta 5.2.x, en la manera en que la funcionalidad vhost del kernel de Linux que traduce los búferes virtueue en IOV, registraba los descriptores del búfer durante una migración. Un usuario invitado privilegiado capaz de pasar descriptores con una longitud no válida hacia el host cuando la migración está en marcha, podría usar este fallo para aumentar sus privilegios sobre el host.
