CVSS: 7.8EPSS: 2%CPEs: 8EXPL: 1CVE-2015-5162 – openstack-nova/glance/cinder: Malicious image may exhaust resources
https://notcve.org/view.php?id=CVE-2015-5162
The image parser in OpenStack Cinder 7.0.2 and 8.0.0 through 8.1.1; Glance before 11.0.1 and 12.0.0; and Nova before 12.0.4 and 13.0.0 does not properly limit qemu-img calls, which might allow attackers to cause a denial of service (memory and disk consumption) via a crafted disk image. El analizador de imagen en OpenStack Cinder 7.0.2 y 8.0.0 hasta la versión 8.1.1; Glance en versiones anteriores a 11.0.1 y 12.0.0; y Nova en versiones anteriores a 12.0.4 y 13.0.0 no limita adecuadamente las llamadas a qemu-img, lo que podría permitir a atacantes provocar una denegación de servicio (consumo de memoria y disco) a través de una imagen de disco manipulada. A resource vulnerability in the OpenStack Compute (nova), Block Storage (cinder), and Image (glance) services was found in their use of qemu-img. An unprivileged user could consume as much as 4 GB of RAM on the compute host by uploading a malicious image. This flaw could lead possibly to host out-of-memory errors and negatively affect other running tenant instances. • http://rhn.redhat.com/errata/RHSA-2016-2923.html http://rhn.redhat.com/errata/RHSA-2016-2991.html http://rhn.redhat.com/errata/RHSA-2017-0153.html http://rhn.redhat.com/errata/RHSA-2017-0156.html http://rhn.redhat.com/errata/RHSA-2017-0165.html http://rhn.redhat.com/errata/RHSA-2017-0282.html http://www.openwall.com/lists/oss-security/2016/10/06/8 http://www.securityfocus.com/bid/76849 https://launchpad.net/bugs/1449062 https://access.redhat.com/securit • CWE-399: Resource Management Errors CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2016-7498
OpenStack Compute (nova) 13.0.0 does not properly delete instances from compute nodes, which allows remote authenticated users to cause a denial of service (disk consumption) by deleting instances while in the resize state. NOTE: this vulnerability exists because of a CVE-2015-3280 regression. OpenStack Compute (nova) 13.0.0 no elimina adecuadamente instancias desde nodos de cómputo, lo que permite a atacantes remotos provocar una denegación de servicio (consumo de disco) mediante la eliminación de instancias durante el estado de cambio de tamaño. NOTA: esta vulnerabilidad existe debido a una regresión de CVE-2015-3280. • http://www.openwall.com/lists/oss-security/2016/09/21/8 http://www.openwall.com/lists/oss-security/2016/09/23/1 http://www.securityfocus.com/bid/93068 https://security.openstack.org/ossa/OSSA-2016-011.html • CWE-399: Resource Management Errors •

https://notcve.org/view.php?id=CVE-2016-2140
The libvirt driver in OpenStack Compute (Nova) before 2015.1.4 (kilo) and 12.0.x before 12.0.3 (liberty), when using raw storage and use_cow_images is set to false, allows remote authenticated users to read arbitrary files via a crafted qcow2 header in an ephemeral or root disk. El controlador libvirt en OpenStack Compute (Nova) en versiones anteriores a 2015.1.4 (kilo) y 12.0.x en versiones anteriores a 12.0.3 (liberty), cuando usa almacenamiento en bruto y use_cow_images está establecido a false, permite a usuarios remotos autenticados leer archivos arbitrarios a través de una cabecera qcow2 manipulada en un disco efímero o root. An information-exposure flaw was found in the OpenStack Compute (nova) resize and migrate functionality. An authenticated user could write a malicious qcow header to an ephemeral or root disk, referencing a block device as a backing file. With a subsequent resize or migration, file system content on the specified device would be leaked to the user. • http://www.openwall.com/lists/oss-security/2016/03/08/6 http://www.securityfocus.com/bid/84277 https://bugs.launchpad.net/nova/+bug/1548450 https://security.openstack.org/ossa/OSSA-2016-007.html https://access.redhat.com/security/cve/CVE-2016-2140 https://bugzilla.redhat.com/show_bug.cgi?id=1313454 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

The volume_utils._parse_volume_info function in OpenStack Compute (Nova) before 2015.1.3 (kilo) and 12.0.x before 12.0.1 (liberty) includes the connection_info dictionary in the StorageError message when using the Xen backend, which might allow attackers to obtain sensitive password information by reading log files or other unspecified vectors. La función volume_utils._parse_volume_info en OpenStack Compute (Nova) en versiones anteriores a 2015.1.3 (kilo) y 12.0.x en versiones anteriores a 12.0.1 (liberty) incluye el diccionario connection_info en el mensaje StorageError cuando utiliza el backend Xen, lo que permitiría a atacantes obtener información sensible de contraseña leyendo archivos de registro u otros vectores no especificados. • http://www.openwall.com/lists/oss-security/2016/01/07/8 http://www.openwall.com/lists/oss-security/2016/01/07/9 http://www.securityfocus.com/bid/80189 https://bugs.launchpad.net/nova/+bug/1516765 https://security.openstack.org/ossa/OSSA-2016-002.html • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2015-7548
OpenStack Compute (Nova) before 2015.1.3 (kilo) and 12.0.x before 12.0.1 (liberty), when using libvirt to spawn instances and use_cow_images is set to false, allow remote authenticated users to read arbitrary files by overwriting an instance disk with a crafted image and requesting a snapshot. OpenStack Compute (Nova) en versiones anteriores a 2015.1.3 (kilo) y 12.0.x en versiones anteriores a 12.0.1 (liberty), cuando se utiliza libvirt para producir instancias y use_cow_images se establece en false, permite a usuarios remotos autenticados leer archivos arbitrarios sobrescribiendo una instancia de disco con una imagen manipulada y solicitando una instantánea. A flaw was discovered in the OpenStack Compute (nova) snapshot feature when using the libvirt driver. A compute user could overwrite an attached instance disk with a malicious header specifying a backing file, and then request a snapshot, causing a file from the compute host to be leaked. This flaw only affects LVM or Ceph setups, or setups using filesystem storage with "use_cow_images = False". • http://rhn.redhat.com/errata/RHSA-2016-0018.html http://www.securityfocus.com/bid/80176 https://security.openstack.org/ossa/OSSA-2016-001.html https://access.redhat.com/security/cve/CVE-2015-7548 https://bugzilla.redhat.com/show_bug.cgi?id=1290511 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
