CVE-2011-1486 – libvirt: error reporting in libvirtd is not thread safe

https://notcve.org/view.php?id=CVE-2011-1486

libvirtd in libvirt before 0.9.0 does not use thread-safe error reporting, which allows remote attackers to cause a denial of service (crash) by causing multiple threads to report errors at the same time. libvirtd de libvirt en versiones anteriores a la 0.9.0 no utiliza el reporte de errores "thread-safe", lo que permite a atacantes remotos provocar una denegación de servicio (caída) provocando que múltiples hilos reporten errores al mismo tiempo. • http://libvirt.org/git/?p=libvirt.git%3Ba=commit%3Bh=f44bfb7fb978c9313ce050a1c4149bf04aa0a670 http://secunia.com/advisories/44459 http://securitytracker.com/id?1025477 http://support.avaya.com/css/P8/documents/100134583 http://www.debian.org/security/2011/dsa-2280 http://www.redhat.com/support/errata/RHSA-2011-0478.html http://www.redhat.com/support/errata/RHSA-2011-0479.html http://www.securityfocus.com/bid/47148 http://www.ubuntu.com/usn/USN-1152-1 https://bugzilla.redhat. • CWE-399: Resource Management Errors •

CVE-2010-2237

https://notcve.org/view.php?id=CVE-2010-2237

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 •

CVE-2010-2238

https://notcve.org/view.php?id=CVE-2010-2238

Red Hat libvirt, possibly 0.7.2 through 0.8.2, recurses into disk-image backing stores without extracting the defined disk backing-store 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 v0.7.2 hasta v0.8.2, se repite en almacenes de respaldo de imagen de disco sin extraer el formato de disco de respaldo definido, lo cual puede permitir a usuarios invitados del Sistema Operativo leer ficheros a su elección en el Sistema Operativo anfitrión, y posiblemente tener otros impactos no especificados, 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=607811 • CWE-264: Permissions, Privileges, and Access Controls •

CVE-2010-2239 – libvirt: not setting user defined backing store format when creating new image

https://notcve.org/view.php?id=CVE-2010-2239

Red Hat libvirt, possibly 0.6.0 through 0.8.2, creates new images without setting the user-defined backing-store format, which allows guest OS users to read arbitrary files on the host OS via unspecified vectors. Red Hat libvirt, posiblemente v0.6.0 hasta v0.8.2, crea nuevas imagenes sin configurar el formato definido por el usuario backing-store, lo que permite a usuarios invitados al SO leer ficheros de su elección en el SO anfitrión a través de vectores sin especificar. • 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 •

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 •
