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.

The storageVolUpload function in storage/storage_driver.c in libvirt before 1.2.11 does not check a certain return value, which allows local users to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted offset value in a "virsh vol-upload" command.

The (1) qemuDomainMigratePerform and (2) qemuDomainMigrateFinish2 functions in qemu/qemu_driver.c in libvirt do not unlock the domain when an ACL check fails, which allow local users to cause a denial of service via unspecified vectors.

The remoteClientFreeFunc function in daemon/remote.c in libvirt before 1.1.3, when ACLs are used, does not set an identity, which causes event handler removal to be denied and remote attackers to cause a denial of service (use-after-free and crash) by registering an event handler and then closing the connection.

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.

The virDomainListPopulate function in conf/domain_conf.c in libvirt before 1.2.9 does not clean up the lock on the list of domains, which allows remote attackers to cause a denial of service (deadlock) via a NULL value in the second parameter in the virConnectListAllDomains API command.

The qemuDomainGetBlockIoTune function in qemu/qemu_driver.c in libvirt before 1.2.9, when a disk has been hot-plugged or removed from the live image, allows remote attackers to cause a denial of service (crash) or read sensitive heap information via a crafted blkiotune query, which triggers an out-of-bounds read.

libvirt 0.7.5 through 1.2.x before 1.2.5 allows local users to cause a denial of service (read block and hang) via a crafted XML document containing an XML external entity declaration in conjunction with an entity reference to the (1) virConnectCompareCPU or (2) virConnectBaselineCPU API method, related to an XML External Entity (XXE) issue. NOTE: this issue was SPLIT per ADT3 due to different affected versions of some vectors. CVE-2014-5177 is used for other API methods.

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.

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.
