CVSS: 6.3EPSS: 0%CPEs: 4EXPL: 1CVE-2021-3631 – libvirt: Insecure sVirt label generation
https://notcve.org/view.php?id=CVE-2021-3631
A flaw was found in libvirt while it generates SELinux MCS category pairs for VMs' dynamic labels. This flaw allows one exploited guest to access files labeled for another guest, resulting in the breaking out of sVirt confinement. The highest threat from this vulnerability is to confidentiality and integrity. Se ha encontrado un fallo en libvirt mientras genera pares de categorías MCS de SELinux para las etiquetas dinámicas de las máquinas virtuales. Este defecto permite que un huésped explotado acceda a archivos etiquetados para otro huésped, resultando en una ruptura del confinamiento de sVirt. • https://access.redhat.com/errata/RHSA-2021:3631 https://bugzilla.redhat.com/show_bug.cgi?id=1977726 https://gitlab.com/libvirt/libvirt/-/commit/15073504dbb624d3f6c911e85557019d3620fdb2 https://gitlab.com/libvirt/libvirt/-/issues/153 https://lists.debian.org/debian-lts-announce/2024/04/msg00000.html https://security.gentoo.org/glsa/202210-06 https://security.netapp.com/advisory/ntap-20220331-0010 https://access.redhat.com/security/cve/CVE-2021-3631 • CWE-732: Incorrect Permission Assignment for Critical Resource •
CVSS: 6.5EPSS: 0%CPEs: 1EXPL: 0CVE-2020-10701
https://notcve.org/view.php?id=CVE-2020-10701
A missing authorization flaw was found in the libvirt API responsible for changing the QEMU agent response timeout. This flaw allows read-only connections to adjust the time that libvirt waits for the QEMU guest agent to respond to agent commands. Depending on the timeout value that is set, this flaw can make guest agent commands fail because the agent cannot respond in time. Unprivileged users with a read-only connection could abuse this flaw to set the response timeout for all guest agent messages to zero, potentially leading to a denial of service. This flaw affects libvirt versions before 6.2.0. • https://bugzilla.redhat.com/show_bug.cgi?id=1819163 https://security.netapp.com/advisory/ntap-20210708-0001 • CWE-862: Missing Authorization •

https://notcve.org/view.php?id=CVE-2021-3559
A flaw was found in libvirt in the virConnectListAllNodeDevices API in versions before 7.0.0. It only affects hosts with a PCI device and driver that supports mediated devices (e.g., GRID driver). This flaw could be used by an unprivileged client with a read-only connection to crash the libvirt daemon by executing the 'nodedev-list' virsh command. The highest threat from this vulnerability is to system availability.

https://notcve.org/view.php?id=CVE-2020-14301
An information disclosure vulnerability was found in libvirt in versions before 6.3.0. HTTP cookies used to access network-based disks were saved in the XML dump of the guest domain. This flaw allows an attacker to access potentially sensitive information in the domain configuration via the `dumpxml` command.

CVSS: 7.2EPSS: 0%CPEs: 3EXPL: 1CVE-2020-25637 – libvirt: double free in qemuAgentGetInterfaces() in qemu_agent.c
https://notcve.org/view.php?id=CVE-2020-25637
A double free memory issue was found to occur in the libvirt API, in versions before 6.8.0, responsible for requesting information about network interfaces of a running QEMU domain. This flaw affects the polkit access control driver. Specifically, clients connecting to the read-write socket with limited ACL permissions could use this flaw to crash the libvirt daemon, resulting in a denial of service, or potentially escalate their privileges on the system. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. Se encontró que ocurría un problema de doble liberación de la memoria en la API de libvirt, en versiones anteriores a 6.8.0, responsable de pedir información sobre unas interfaces de red de un dominio QEMU en ejecución. • https://github.com/brahmiboudjema/CVE-2020-25637-libvirt-double-free http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00072.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00073.html https://bugzilla.redhat.com/show_bug.cgi?id=1881037 https://lists.debian.org/debian-lts-announce/2024/04/msg00000.html https://security.gentoo.org/glsa/202210-06 https://access.redhat.com/security/cve/CVE-2020-25637 • CWE-415: Double Free •
