CVE-2014-3573 – Engine: XML eXternal Entity (XXE) flaw in backend module
https://notcve.org/view.php?id=CVE-2014-3573
The oVirt Engine backend module, as used in Red Hat Enterprise Virtualization Manager before 3.4.2, uses an "insecure DocumentBuilderFactory," which allows remote attackers to read arbitrary files or possibly have other unspecified impact via a crafted XML/RSDL document, related to an XML External Entity (XXE) issue. El módulo de backend oVirt Engine, como el utilizado en Red Hat Enterprise Virtualization Manager anterior a 3.4.2, utiliza una 'DocumentBuilderFactory insegura', lo que permite a atacantes remotos leer archivos arbitrarios o, posiblemente, tener otro impacto sin especificar a través de un documento XML/RSDL manipulado, relacionado con un problema de tipo XML External Entity (XXE). It was discovered that, when loading XML/RSDL documents, the oVirt Engine back end module used an insecure DocumentBuilderFactory. A remote, authenticated attacker could use this flaw to read files accessible to the user running the ovirt-engine server, and potentially perform other more advanced XML External Entity (XXE) attacks. • http://rhn.redhat.com/errata/RHSA-2014-1161.html http://www.securitytracker.com/id/1030807 https://access.redhat.com/security/cve/CVE-2014-3573 https://bugzilla.redhat.com/show_bug.cgi?id=1125795 • CWE-20: Improper Input Validation CWE-611: Improper Restriction of XML External Entity Reference •
CVE-2014-3559 – ovirt-engine-backend: memory snapshots not wiped when deleting a VM with wipe-after-delete (WAD) enabled for its disks
https://notcve.org/view.php?id=CVE-2014-3559
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. El backend de almacenaje oVirt en Red Hat Enterprise Virtualization 3.4 no borra instantáneas de la memoria cuando elimina una VM, incluso cuando borrar después de eliminar (wipe-after-delete o WAD) está configurado para el disco de la VM, lo que permite a usuarios remotos autenticados con ciertas credenciales leer porciones de la memoria eliminada de la VM y obtener información sensible a través de un volumen de almacenaje no inicializado. It was found that the oVirt storage back end did not wipe memory snapshots when VMs were deleted, even if wipe-after-delete (WAD) was enabled for the VM's disks. A remote attacker with credentials to create a new VM could use this flaw to potentially access the contents of memory snapshots in an uninitialized storage volume, possibly leading to the disclosure of sensitive information. • http://rhn.redhat.com/errata/RHSA-2014-1002.html http://www.securitytracker.com/id/1030664 https://bugzilla.redhat.com/show_bug.cgi?id=1121925 https://exchange.xforce.ibmcloud.com/vulnerabilities/95098 https://access.redhat.com/security/cve/CVE-2014-3559 • CWE-212: Improper Removal of Sensitive Information Before Storage or Transfer CWE-264: Permissions, Privileges, and Access Controls •
CVE-2014-5177 – libvirt: unsafe parsing of XML documents allows libvirt DoS and/or arbitrary file read
https://notcve.org/view.php?id=CVE-2014-5177
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. libvirt 1.0.0 hasta 1.2.x anterior a 1.2.5, cuando el control de acceso detallado está habilitado, permite a usuarios locales leer ficheros arbitrarios a través de un documento XML manipulado que contiene una declaración de entidad externa XML en conjunto con una referencia de entidad en el método API (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 o (19) virConnectBaselineCPU, relacionado con un problema de entidad externa XML (XXE). NOTA: este problema ha sido dividido (SPLIT) del CVE-2014-0179 por ADT3 debido a las diferentes versiones afectadas de algunos vectores. It was found that libvirt passes the XML_PARSE_NOENT flag when parsing XML documents using the libxml2 library, in which case all XML entities in the parsed documents are expanded. A user able to force libvirtd to parse an XML document with an entity pointing to a file could use this flaw to read the contents of that file (limited to libvirt as shipped with Red Hat Enterprise Linux 7); parsing an XML document with an entity pointing to a special file that blocks on read access could cause libvirtd to hang indefinitely, resulting in a denial of service on the system. • http://libvirt.org/news.html http://lists.opensuse.org/opensuse-updates/2014-05/msg00048.html http://lists.opensuse.org/opensuse-updates/2014-05/msg00052.html http://rhn.redhat.com/errata/RHSA-2014-0560.html http://secunia.com/advisories/60895 http://security.gentoo.org/glsa/glsa-201412-04.xml http://security.libvirt.org/2014/0003.html http://www.ubuntu.com/usn/USN-2366-1 https://access.redhat.com/security/cve/CVE-2014-5177 https://bugzilla.redhat.com/show_bug.cg • CWE-20: Improper Input Validation CWE-611: Improper Restriction of XML External Entity Reference •
