CVE-2014-3672 2 Redhat, Xen 2 Libvirt, Xen 2023-02-13 2.1 LOW 6.5 MEDIUM
The qemu implementation in libvirt before 1.3.0 and Xen allows local guest OS users to cause a denial of service (host disk consumption) by writing to stdout or stderr.
CVE-2013-6456 2 Fedoraproject, Redhat 2 Fedora, Libvirt 2023-02-13 5.8 MEDIUM N/A
The LXC driver (lxc/lxc_driver.c) in libvirt 1.0.1 through 1.2.1 allows local users to (1) delete arbitrary host devices via the virDomainDeviceDettach API and a symlink attack on /dev in the container; (2) create arbitrary nodes (mknod) via the virDomainDeviceAttach API and a symlink attack on /dev in the container; and cause a denial of service (shutdown or reboot host OS) via the (3) virDomainShutdown or (4) virDomainReboot API and a symlink attack on /dev/initctl in the container, related to "paths under /proc/$PID/root" and the virInitctlSetRunLevel function.
CVE-2013-6436 1 Redhat 1 Libvirt 2023-02-13 2.1 LOW N/A
The lxcDomainGetMemoryParameters method in lxc/lxc_driver.c in libvirt 1.0.5 through 1.2.0 does not properly check the status of LXC guests when reading memory tunables, which allows local users to cause a denial of service (NULL pointer dereference and libvirtd crash) via a guest in the shutdown status, as demonstrated by the "virsh memtune" command.
CVE-2013-4296 2 Canonical, Redhat 3 Ubuntu Linux, Enterprise Linux, Libvirt 2023-02-13 4.0 MEDIUM N/A
The remoteDispatchDomainMemoryStats function in daemon/remote.c in libvirt 0.9.1 through 0.10.1.x, 0.10.2.x before 0.10.2.8, 1.0.x before 1.0.5.6, and 1.1.x before 1.1.2 allows remote authenticated users to cause a denial of service (uninitialized pointer dereference and crash) via a crafted RPC call.
CVE-2012-4423 1 Redhat 1 Libvirt 2023-02-13 5.0 MEDIUM N/A
The virNetServerProgramDispatchCall function in libvirt before 0.10.2 allows remote attackers to cause a denial of service (NULL pointer dereference and segmentation fault) via an RPC call with (1) an event as the RPC number or (2) an RPC number whose value is in a "gap" in the RPC dispatch table.
CVE-2019-3886 3 Fedoraproject, Opensuse, Redhat 3 Fedora, Leap, Libvirt 2023-02-12 4.8 MEDIUM 5.4 MEDIUM
An incorrect permissions check was discovered in libvirt 4.8.0 and above. The readonly permission was allowed to invoke APIs depending on the guest agent, which could lead to potentially disclosing unintended information or denial of service by causing libvirt to block.
CVE-2019-10132 2 Fedoraproject, Redhat 2 Fedora, Libvirt 2023-02-12 6.5 MEDIUM 8.8 HIGH
A vulnerability was found in libvirt >= 4.1.0 in the virtlockd-admin.socket and virtlogd-admin.socket systemd units. 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.
CVE-2016-5008 2 Debian, Redhat 2 Debian Linux, Libvirt 2023-02-12 4.3 MEDIUM 9.8 CRITICAL
libvirt before 2.0.0 improperly disables password checking when the password on a VNC server is set to an empty string, which allows remote attackers to bypass authentication and establish a VNC session by connecting to the server.
CVE-2015-0236 4 Canonical, Mageia, Opensuse and 1 more 8 Ubuntu Linux, Mageia, Opensuse and 5 more 2023-02-12 3.5 LOW N/A
libvirt before 1.2.12 allow remote authenticated users to obtain the VNC password by using the VIR_DOMAIN_XML_SECURE flag with a crafted (1) snapshot to the virDomainSnapshotGetXMLDesc interface or (2) image to the virDomainSaveImageGetXMLDesc interface.
CVE-2020-14339 1 Redhat 2 Enterprise Linux, Libvirt 2022-11-07 7.2 HIGH 8.8 HIGH
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 their standard permissions, potentially causing serious damage to the host operating system. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
CVE-2020-14301 2 Netapp, Redhat 13 Ontap Select Deploy Administration Utility, Codeready Linux Builder, Enterprise Linux and 10 more 2022-05-13 4.0 MEDIUM 6.5 MEDIUM
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.
CVE-2020-10701 1 Redhat 1 Libvirt 2022-05-13 4.0 MEDIUM 6.5 MEDIUM
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.
CVE-2021-3559 2 Netapp, Redhat 2 Ontap Select Deploy Administration Utility, Libvirt 2022-04-26 4.0 MEDIUM 6.5 MEDIUM
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.
CVE-2019-10167 1 Redhat 9 Enterprise Linux, Enterprise Linux Desktop, Enterprise Linux Server and 6 more 2020-10-15 4.6 MEDIUM 7.8 HIGH
The virConnectGetDomainCapabilities() libvirt API, versions 4.x.x before 4.10.1 and 5.x.x before 5.4.1, accepts an "emulatorbin" 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.
CVE-2019-10168 1 Redhat 9 Enterprise Linux, Enterprise Linux Desktop, Enterprise Linux Server and 6 more 2020-10-15 4.6 MEDIUM 7.8 HIGH
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.
CVE-2018-5748 2 Debian, Redhat 8 Debian Linux, Enterprise Linux Desktop, Enterprise Linux Server and 5 more 2020-10-15 5.0 MEDIUM 7.5 HIGH
qemu/qemu_monitor.c in libvirt allows attackers to cause a denial of service (memory consumption) via a large QEMU reply.
CVE-2019-10166 1 Redhat 9 Enterprise Linux, Enterprise Linux Desktop, Enterprise Linux Server and 6 more 2020-10-15 4.6 MEDIUM 7.8 HIGH
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.
CVE-2018-6764 3 Canonical, Debian, Redhat 7 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 4 more 2019-10-03 4.6 MEDIUM 7.8 HIGH
util/virlog.c in libvirt does not properly determine the hostname on LXC container startup, which allows local guest OS users to bypass an intended container protection mechanism and execute arbitrary commands via a crafted NSS module.
CVE-2016-10746 2 Debian, Redhat 2 Debian Linux, Libvirt 2019-05-01 5.0 MEDIUM 7.5 HIGH
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.
CVE-2013-4311 2 Canonical, Redhat 3 Ubuntu Linux, Enterprise Linux, Libvirt 2019-04-22 4.6 MEDIUM N/A
libvirt 1.0.5.x before 1.0.5.6, 0.10.2.x before 0.10.2.8, and 0.9.12.x before 0.9.12.2 allows local users to bypass intended access restrictions by leveraging a PolkitUnixProcess PolkitSubject race condition in pkcheck via a (1) setuid process or (2) pkexec process, a related issue to CVE-2013-4288.
