CVSS: 6.9EPSS: 7%CPEs: 1EXPL: 0CVE-2011-1146 – libvirt: several API calls do not honour read-only connection
https://notcve.org/view.php?id=CVE-2011-1146
libvirt.c in the API in Red Hat libvirt 0.8.8 does not properly restrict operations in a read-only connection, which allows remote attackers to cause a denial of service (host OS crash) or possibly execute arbitrary code via a (1) virNodeDeviceDettach, (2) virNodeDeviceReset, (3) virDomainRevertToSnapshot, (4) virDomainSnapshotDelete, (5) virNodeDeviceReAttach, or (6) virConnectDomainXMLToNative call, a different vulnerability than CVE-2008-5086. libvirt.c en la API de Red Hat libvirt v0.8.8 no restringe correctamente las operaciones en una conexión de solo lectura, lo que podría permitir a atacantes remotos provocar una denegación de servicio (caida del sistema operativo) o posiblemente ejecutar código de su elección a través de una llamada (1) virNodeDeviceDettach, (2) virNodeDeviceReset, (3) virDomainRevertToSnapshot, (4) virDomainSnapshotDelete, (5) virNodeDeviceReAttach, o (6) virConnectDomainXMLToNative, una vulnerabilidad diferente de CVE-2008-5086. • http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=617773 http://libvirt.org/git/?p=libvirt.git%3Ba=commit%3Bh=71753cb7f7a16ff800381c0b5ee4e99eea92fed3 http://lists.fedoraproject.org/pipermail/package-announce/2011-March/056209.html http://lists.opensuse.org/opensuse-updates/2011-04/msg00022.html http://openwall.com/lists/oss-security/2011/03/09/3 http://openwall.com/lists/oss-security/2011/03/10/5 http://secunia.com/advisories/43670 http://secunia.com/advisories/43780 http://secunia& • CWE-264: Permissions, Privileges, and Access Controls •

Red Hat libvirt, possibly 0.6.1 through 0.8.2, looks up disk backing stores without referring to the user-defined main disk format, which might allow guest OS users to read arbitrary files on the host OS, and possibly have unspecified other impact, via unknown vectors. Red Hat libvirt, posiblemente v0.6.1 hasta v0.8.2, busca almacenes de respaldo de discos sin hacer referencia al formato del disco definido por el usuario principal, lo que podría permitir a usuarios invitados al SO leer ficheros de su elección en el SO anfitrión, y posiblemente tenga otro impacto sin especificar, a través de vectores desconocidos. • http://libvirt.org/news.html http://lists.fedoraproject.org/pipermail/package-announce/2010-July/044520.html http://lists.fedoraproject.org/pipermail/package-announce/2010-July/044579.html http://lists.opensuse.org/opensuse-security-announce/2010-09/msg00006.html http://ubuntu.com/usn/usn-1008-1 http://ubuntu.com/usn/usn-1008-2 http://ubuntu.com/usn/usn-1008-3 http://www.vupen.com/english/advisories/2010/2763 https://bugzilla.redhat.com/show_bug.cgi?id=607810 • CWE-264: Permissions, Privileges, and Access Controls •

https://notcve.org/view.php?id=CVE-2010-2242
Red Hat libvirt 0.2.0 through 0.8.2 creates iptables rules with improper mappings of privileged source ports, which allows guest OS users to bypass intended access restrictions by leveraging IP address and source-port values, as demonstrated by copying and deleting an NFS directory tree. Red Hat libvirt v0.2.0 hasta v0.8.2 crea reglas de iptable con asignaciones inadecuadas de puertos de origen privilegiados, lo que permite a usuarios invitados del SO evitar las restricciones de acceso establecidas aprovechando los valores de dirección IP y puerto-origen, como se ha demostrado copiando y eliminando un arbol de ficheros NFS. • http://libvirt.org/news.html http://lists.fedoraproject.org/pipermail/package-announce/2010-July/044520.html http://lists.fedoraproject.org/pipermail/package-announce/2010-July/044579.html http://lists.opensuse.org/opensuse-security-announce/2010-09/msg00006.html http://ubuntu.com/usn/usn-1008-1 http://ubuntu.com/usn/usn-1008-2 http://ubuntu.com/usn/usn-1008-3 http://www.redhat.com/support/errata/RHSA-2010-0615.html http://www.vupen.com/english/advisories/2010/2062 http • CWE-264: Permissions, Privileges, and Access Controls •
