UBUNTU-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...

ALPINE-CVE-2020-14339

A flaw was found in libvirt, where it leaked a file descriptor for /dev/mapper/control into the QEMU process. This file descriptor allows for privileged operations to happen against the device-mapper on the host. This flaw allows a malicious guest user or process to perform operations outside of...

libvirt: arbitrary file read/exec via virDomainSaveImageGetXMLDesc API

It was discovered that libvirtd would permit read-only clients to use the virDomainSaveImageGetXMLDesc API, specifying an arbitrary path which would be accessed with the permissions of the libvirtd process. An attacker with access to the libvirtd socket could use this to probe the existence of...

libvirt: wrong permissions in systemd admin-sock due to missing SocketMode parameter

A flaw was found in libvirt in version 4.1.0 and earlier. A missing SocketMode configuration parameter allows any user on the host to connect using virtlockd-admin-sock or virtlogd-admin-sock and perform administrative tasks against the virtlockd and virtlogd daemons. The highest threat from this...

DEBIAN-CVE-2010-2239

Red Hat libvirt, possibly 0.6.0 through 0.8.2, creates new images without setting the user-defined backing-store format, which allows guest OS users to read arbitrary files on the host OS via unspecified vectors...
