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-2019-10161 2 Canonical, Redhat 5 Ubuntu Linux, Enterprise Linux, Libvirt and 2 more 2021-03-25 7.2 HIGH 7.8 HIGH
It was discovered that libvirtd before versions 4.10.1 and 5.4.1 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 arbitrary files, cause denial of service or cause libvirtd to execute arbitrary programs.
CVE-2017-1000256 2 Debian, Redhat 2 Debian Linux, Libvirt 2020-11-16 6.8 MEDIUM 8.1 HIGH
libvirt version 2.3.0 and later is vulnerable to a bad default configuration of "verify-peer=no" passed to QEMU by libvirt resulting in a failure to validate SSL/TLS certificates by default.
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-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-2019-10166 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-2018-5748 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-2020-10703 1 Redhat 1 Libvirt 2020-06-15 4.0 MEDIUM 6.5 MEDIUM
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.
CVE-2020-12430 1 Redhat 2 Enterprise Linux, Libvirt 2020-06-15 4.0 MEDIUM 6.5 MEDIUM
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.
CVE-2017-2635 1 Redhat 1 Libvirt 2019-10-09 4.0 MEDIUM 6.5 MEDIUM
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.
CVE-2018-6764 3 Canonical, Debian, Redhat 7 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 4 more 2019-10-02 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-2019-3840 2 Opensuse, Redhat 2 Leap, Libvirt 2019-05-04 3.5 LOW 6.3 MEDIUM
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.
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-2014-5177 2 Opensuse, Redhat 4 Opensuse, Enterprise Linux, Enterprise Virtualization and 1 more 2019-04-22 1.2 LOW N/A
libvirt 1.0.0 through 1.2.x before 1.2.5, when fine grained access control is enabled, allows local users to read arbitrary files via a crafted XML document containing an XML external entity declaration in conjunction with an entity reference to the (1) virDomainDefineXML, (2) virNetworkCreateXML, (3) virNetworkDefineXML, (4) virStoragePoolCreateXML, (5) virStoragePoolDefineXML, (6) virStorageVolCreateXML, (7) virDomainCreateXML, (8) virNodeDeviceCreateXML, (9) virInterfaceDefineXML, (10) virStorageVolCreateXMLFrom, (11) virConnectDomainXMLFromNative, (12) virConnectDomainXMLToNative, (13) virSecretDefineXML, (14) virNWFilterDefineXML, (15) virDomainSnapshotCreateXML, (16) virDomainSaveImageDefineXML, (17) virDomainCreateXMLWithFiles, (18) virConnectCompareCPU, or (19) virConnectBaselineCPU API method, related to an XML External Entity (XXE) issue. NOTE: this issue was SPLIT from CVE-2014-0179 per ADT3 due to different affected versions of some vectors.
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.
CVE-2013-7336 2 Opensuse, Redhat 2 Opensuse, Libvirt 2018-10-30 1.9 LOW N/A
The qemuMigrationWaitForSpice function in qemu/qemu_migration.c in libvirt before 1.1.3 does not properly enter a monitor when performing seamless SPICE migration, which allows local users to cause a denial of service (NULL pointer dereference and libvirtd crash) by causing domblkstat to be called at the same time as the qemuMonitorGetSpiceMigrationStatus function.
CVE-2018-1064 2 Debian, Redhat 2 Debian Linux, Libvirt 2018-06-19 5.0 MEDIUM 7.5 HIGH
libvirt version before 4.2.0-rc1 is vulnerable to a resource exhaustion as a result of an incomplete fix for CVE-2018-5748 that affects QEMU monitor but now also triggered via QEMU guest agent.
CVE-2014-7823 1 Redhat 1 Libvirt 2017-01-02 5.0 MEDIUM N/A
The virDomainGetXMLDesc API in Libvirt before 1.2.11 allows remote read-only users to obtain the VNC password by using the VIR_DOMAIN_XML_MIGRATABLE flag, which triggers the use of the VIR_DOMAIN_XML_SECURE flag.
CVE-2015-5247 2 Canonical, Redhat 2 Ubuntu Linux, Libvirt 2016-04-18 4.0 MEDIUM 6.5 MEDIUM
The virStorageVolCreateXML API in libvirt 1.2.14 through 1.2.19 allows remote authenticated users with a read-write connection to cause a denial of service (libvirtd crash) by triggering a failed unlink after creating a volume on a root_squash NFS pool.
CVE-2014-8131 1 Redhat 1 Libvirt 2015-01-06 4.0 MEDIUM N/A
The qemu implementation of virConnectGetAllDomainStats in libvirt before 1.2.11 does not properly handle locks when a domain is skipped due to ACL restrictions, which allows a remote authenticated users to cause a denial of service (deadlock or segmentation fault and crash) via a request to access the users does not have privileges to access.
