Enterprise Virtualization

VDSM and libvirt in Red Hat Enterprise Virtualization Hypervisor (aka RHEV-H) 7-7.x before 7-7.2-20151119.0 and 6-6.x before 6-6.7-20151117.0 as packaged in Red Hat Enterprise Virtualization before 3.5.6 when VSDM is run with -spice disable-ticketing and a VM is suspended and then restored, allows remote attackers to log in without authentication via unspecified vectors.Show less

When updating a password in the rhvm database the ovirt-aaa-jdbc-tool tools before 1.1.3 fail to correctly check for the current password if it is expired. This would allow access to an attacker with access to change the password on accounts with expired passwords, gaining access to those accounts.Show less

ovirt-ansible-roles before version 1.0.6 has a vulnerability due to a missing no_log directive, resulting in the 'Add oVirt Provider to ManageIQ/CloudForms' playbook inadvertently disclosing admin passwords in the provisioning log. In an environment where logs are shared with other parties, this could lead to privilege escalation.Show less

DHCP packages in Red Hat Enterprise Linux 6 and 7, Fedora 28, and earlier are vulnerable to a command injection flaw in the NetworkManager integration script included in the DHCP client. A malicious DHCP server, or an attacker on the local network able to spoof DHCP responses, could use this flaw to execute arbitrary commands with root privileges on systems using NetworkManager and configured to obtain network configuration using the DHCP protocol.Show less

ovirt-engine API and administration web portal before versions 4.2.2.5, 4.1.11.2 is vulnerable to an exposure of Power Management credentials, including cleartext passwords to Host Administrators. A Host Administrator could use this flaw to gain access to the power management systems of hosts they control.Show less

ovirt-engine-webadmin, as used in Red Hat Enterprise Virtualization Manager (aka RHEV-M) for Servers and RHEV-M 4.0, allows physically proximate attackers to bypass a webadmin session timeout restriction via vectors related to UI selections, which trigger repeating queries.Show less

The Floppy Disk Controller (FDC) in QEMU, as used in Xen 4.5.x and earlier and KVM, allows local guest users to cause a denial of service (out-of-bounds write and guest crash) or possibly execute arbitrary code via the (1) FD_CMD_READ_ID, (2) FD_CMD_DRIVE_SPECIFICATION_COMMAND, or other unspecified commands, aka VENOM.Show less

The rhevm-log-collector package in Red Hat Enterprise Virtualization 3.4 uses the PostgreSQL database password on the command line when calling sosreport, which allows local users to obtain sensitive information by listing the processes.Show less

The oVirt storage backend in Red Hat Enterprise Virtualization 3.4 does not wipe memory snapshots when deleting a VM, even when wipe-after-delete (WAD) is configured for the VM's disk, which allows remote authenticated users with certain credentials to read portions of the deleted VM's memory and obtain sensitive information via an uninitialized storage volume.Show less

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.Show less

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.Show less

The REST API in the ovirt-engine in oVirt, as used in Red Hat Enterprise Virtualization (rhevm) 3.4, allows remote authenticated users to read arbitrary files and have other unspecified impact via unknown vectors, related to an XML External Entity (XXE) issue.Show less

The vfprintf function in stdio-common/vfprintf.c in GNU C Library (aka glibc) 2.5, 2.12, and probably other versions does not "properly restrict the use of" the alloca function when allocating the SPECS array, which allows context-dependent attackers to bypass the FORTIFY_SOURCE format-string protection mechanism and cause a denial of service (crash) or possibly execute arbitrary code via a crafted format string using positional parameters and a large number of format specifiers, a different vulnerability than CVE-2012-3404 and CVE-2012-3405.Show less

The vfprintf function in stdio-common/vfprintf.c in libc in GNU C Library (aka glibc) 2.14 and other versions does not properly calculate a buffer length, which allows context-dependent attackers to bypass the FORTIFY_SOURCE format-string protection mechanism and cause a denial of service (segmentation fault and crash) via a format string with a large number of format specifiers that triggers "desynchronization within the buffer size handling," a different vulnerability than CVE-2012-3404.Show less
