libvirt-domain.c in libvirt before 1.3.1 supports virDomainGetTime API calls by guest agents with an RO connection, even though an RW connection was supposed to be required, a different vulnerability than CVE-2019-3886. libvirt-domain.c en libvirt versiones anteriores a la 1.3.1 soporta las llamadas a la API virDomainGetTime por agentes invitados con una conexión RO, aunque se suponía que se requería una conexión RW, es una vulnerabilidad diferente de CVE-2019-3886. • https://github.com/libvirt/libvirt/commit/506e9d6c2d4baaf580d489fff0690c0ff2ff588f https://github.com/libvirt/libvirt/compare/11288f5...8fd6867 https://lists.debian.org/debian-lts-announce/2019/04/msg00032.html • CWE-254: 7PK - Security Features •
CVSS: 6.3EPSS: 0%CPEs: 3EXPL: 3CVE-2019-3840 – libvirt: NULL pointer dereference after running qemuAgentCommand in qemuAgentGetInterfaces function
https://notcve.org/view.php?id=CVE-2019-3840
A NULL pointer dereference flaw was discovered in libvirt before version 5.0.0 in the way it gets interface information through the QEMU agent. An attacker in a guest VM can use this flaw to crash libvirtd and cause a denial of service. Se ha descubierto un error de desreferencia de puntero NULL en libvirt, en versiones anteriores a la 5.0.0, en la forma en la que obtiene información de la interfaz mediante el agente QEMU. Un atacante en una máquina virtual invitada puede emplear este error para provocar el cierre inesperado de libvirtd y provocar una denegación de servicio (DoS).

A NULL pointer deference flaw was found in the way libvirt from 2.5.0 to 3.0.0 handled empty drives. A remote authenticated attacker could use this flaw to crash libvirtd daemon resulting in denial of service. Se ha detectado un defecto de desferencia del puntero NULL en la forma en la que libvirt desde la versión 2.5.0 hasta la 3.0.0 manejaba las unidades vacías. Un atacante autenticado remoto podría usar este defecto para provocar el cierre inesperado del demonio libvirtd, lo que provocaría una denegación de servicio (DoS). • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2017-2635 https://libvirt.org/git/?p=libvirt.git%3Ba=commit%3Bh=c3de387380f6057ee0e46cd9f2f0a092e8070875 • CWE-476: NULL Pointer Dereference •
