CVE-2010-2242 – libvirt: improperly mapped source privileged ports may allow for obtaining privileged resources on the host

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 •
