CVSS: 6.5EPSS: 0%CPEs: 1EXPL: 1CVE-2020-10703 – libvirt: Potential denial of service via active pool without target path
https://notcve.org/view.php?id=CVE-2020-10703
A NULL pointer dereference was found in the libvirt API responsible introduced in upstream version 3.10.0, and fixed in libvirt 6.0.0, for fetching a storage pool based on its target path. In more detail, this flaw affects storage pools created without a target path such as network-based pools like gluster and RBD. Unprivileged users with a read-only connection could abuse this flaw to crash the libvirt daemon, resulting in a potential denial of service. Se detectó una desreferencia del puntero NULL en la API libvirt responsable que la introdujo en la versión anterior a 3.10.0, y corregida en libvirt versión 6.0.0, para extraer un grupo de almacenamiento basado en su ruta de destino. En más detalle, este fallo afecta a los grupos de almacenamiento creados sin una ruta de destino, tales como los grupos basados en red tales como Gluster y RBD. • https://bugzilla.redhat.com/show_bug.cgi?id=1790725 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10703 https://libvirt.org/git/?p=libvirt.git%3Ba=commit%3Bh=5d5c732d748d644ec14626bce448e84bdc4bd93e https://libvirt.org/git/?p=libvirt.git%3Ba=commit%3Bh=7aa0e8c0cb8a6293d0c6f7e3d29c13b96dec2129 https://libvirt.org/git/? • CWE-476: NULL Pointer Dereference •

An issue was discovered in qemuDomainGetStatsIOThread in qemu/qemu_driver.c in libvirt 4.10.0 though 6.x before 6.1.0. A memory leak was found in the virDomainListGetStats libvirt API that is responsible for retrieving domain statistics when managing QEMU guests. This flaw allows unprivileged users with a read-only connection to cause a memory leak in the domstats command, resulting in a potential denial of service. Se descubrió un problema en la función qemuDomainGetStatsIOThread en el archivo qemu/qemu_driver.c en libvirt versiones 4.10.0 hasta 6.x anteriores a 6.1.0. Se encontró una pérdida de memoria en la API libDirt de virDomainListGetStats que es responsable de recuperar las estadísticas del dominio al administrar invitados de QEMU. • https://bugzilla.redhat.com/show_bug.cgi?id=1804548 https://bugzilla.redhat.com/show_bug.cgi?id=1828190 https://libvirt.org/git/?p=libvirt.git%3Ba=commit%3Bh=9bf9e0ae6af38c806f4672ca7b12a6b38d5a9581 https://lists.debian.org/debian-lts-announce/2024/04/msg00000.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/D5GE6ISYUL3CIWO3FQRUGMKTKP2NYED2 https://security.netapp.com/advisory/ntap-20200518-0003 https://usn.ubuntu.com/4371-1 • CWE-401: Missing Release of Memory after Effective Lifetime •
CVSS: 5.8EPSS: 0%CPEs: 5EXPL: 0CVE-2019-20485 – libvirt: Potential DoS by holding a monitor job while querying QEMU guest-agent
https://notcve.org/view.php?id=CVE-2019-20485
qemu/qemu_driver.c in libvirt before 6.0.0 mishandles the holding of a monitor job during a query to a guest agent, which allows attackers to cause a denial of service (API blockage). El archivo qemu/qemu_driver.c en libvirt versiones anteriores a 6.0.0, maneja inapropiadamente la conservación de un trabajo de monitoreo durante una consulta a un agente invitado, lo que permite a atacantes causar una denegación de servicio (bloqueo de la API). A flaw was found in the way the libvirtd daemon issued the 'suspend' command to a QEMU guest-agent running inside a guest, where it holds a monitor job while issuing the 'suspend' command to a guest-agent. A malicious guest-agent may use this flaw to block the libvirt daemon indefinitely, resulting in a denial of service. • https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=953078 https://bugzilla.redhat.com/show_bug.cgi?id=1809740 https://libvirt.org/git/?p=libvirt.git%3Ba=commit%3Bh=a663a860819287e041c3de672aad1d8543098ecc https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/D5GE6ISYUL3CIWO3FQRUGMKTKP2NYED2 https://security-tracker.debian.org/tracker/CVE-2019-20485 https://www.mail-archive.com/debian-bugs-dist%40lists.debian.org/msg1730509.html https://access.redhat.com/security/cve/CVE-2019 • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •
CVSS: 8.8EPSS: 0%CPEs: 14EXPL: 0CVE-2019-10168 – libvirt: arbitrary command execution via virConnectBaselineHypervisorCPU and virConnectCompareHypervisorCPU APIs
https://notcve.org/view.php?id=CVE-2019-10168
The virConnectBaselineHypervisorCPU() and virConnectCompareHypervisorCPU() libvirt APIs, 4.x.x before 4.10.1 and 5.x.x before 5.4.1, accept an "emulator" argument to specify the program providing emulation for a domain. Since v1.2.19, libvirt will execute that program to probe the domain's capabilities. Read-only clients could specify an arbitrary path for this argument, causing libvirtd to execute a crafted executable with its own privileges. Las APIs libvirt de las funciones virConnectBaselineHypervisorCPU() y virConnectCompareHypervisorCPU(), versiones 4.x.x anteriores a 4.10.1 y versiones 5.x.x anteriores a 5.4.1, aceptan un argumento "emulator" para especificar el programa que proporciona emulación para un dominio. Desde versión v1.2.19, libvirt ejecutará ese programa para examinar las capacidades del dominio. • https://access.redhat.com/libvirt-privesc-vulnerabilities https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-10168 https://security.gentoo.org/glsa/202003-18 https://access.redhat.com/security/cve/CVE-2019-10168 https://bugzilla.redhat.com/show_bug.cgi?id=1720118 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-250: Execution with Unnecessary Privileges CWE-284: Improper Access Control •

https://notcve.org/view.php?id=CVE-2019-10166
It was discovered that libvirtd, versions 4.x.x before 4.10.1 and 5.x.x before 5.4.1, would permit readonly clients to use the virDomainManagedSaveDefineXML() API, which would permit them to modify managed save state files. If a managed save had already been created by a privileged user, a local attacker could modify this file such that libvirtd would execute an arbitrary program when the domain was resumed. Se detectó que libvirtd, versiones 4.x.x anteriores a 4.10.1 y versiones 5.x.x anteriores a 5.4.1, permitiría a los clientes de solo lectura utilizar la API de la función virDomainManagedSaveDefineXML(), lo que les permitiría modificar archivos de estado managed save. Si un managed save ya ha sido creado por un usuario privilegiado, un atacante local podría modificar este archivo de manera que libvirtd ejecutaría un programa arbitrario cuando el dominio esté reanudado.
