CVSS: 6.8EPSS: 2%CPEs: 110EXPL: 0CVE-2013-6458 – qemu: job usage issue in several APIs leading to libvirtd crash
https://notcve.org/view.php?id=CVE-2013-6458
Multiple race conditions in the (1) virDomainBlockStats, (2) virDomainGetBlockInf, (3) qemuDomainBlockJobImpl, and (4) virDomainGetBlockIoTune functions in libvirt before 1.2.1 do not properly verify that the disk is attached, which allows remote read-only attackers to cause a denial of service (libvirtd crash) via the virDomainDetachDeviceFlags command. Múltiples condiciones de carrera en las funciones (1) virDomainBlockStats, (2) virDomainGetBlockInf, (3) qemuDomainBlockJobImpl y (4) virDomainGetBlockIoTune en libvirt anteriores a 1.2.1 no verifica correctamente que el disco esté conectado, lo cual permite a atacantes remotos con permisos de sólo lectura causar denegación de servicio (caída de libvirtd) a través del comando virDomainDetachDeviceFlags. • http://libvirt.org/news.html http://lists.opensuse.org/opensuse-updates/2014-02/msg00060.html http://lists.opensuse.org/opensuse-updates/2014-02/msg00062.html http://rhn.redhat.com/errata/RHSA-2014-0103.html http://secunia.com/advisories/56186 http://secunia.com/advisories/56446 http://secunia.com/advisories/60895 http://security.gentoo.org/glsa/glsa-201412-04.xml http://www.debian.org/security/2014/dsa-2846 http://www.ubuntu.com/usn/USN-2093-1 https://bugzilla • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

https://notcve.org/view.php?id=CVE-2014-1447
Race condition in the virNetServerClientStartKeepAlive function in libvirt before 1.2.1 allows remote attackers to cause a denial of service (libvirtd crash) by closing a connection before a keepalive response is sent. Condición de carrera en la función virNetServerClientStartKeepAlive en libvirt anteriores a 1.2.1 permite a atacantes remotos causar denegación de servicio (caída de libvirtd) mediante el cierre de conexiones antes de que una respuesta keepalive sea enviada. • https://github.com/tagatac/libvirt-CVE-2014-1447 http://libvirt.org/news.html http://lists.opensuse.org/opensuse-updates/2014-02/msg00060.html http://lists.opensuse.org/opensuse-updates/2014-02/msg00062.html http://rhn.redhat.com/errata/RHSA-2014-0103.html http://secunia.com/advisories/56321 http://secunia.com/advisories/56446 http://secunia.com/advisories/60895 http://security.gentoo.org/glsa/glsa-201412-04.xml http://www.debian.org/security/2014/dsa-2846 http:// • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

https://notcve.org/view.php?id=CVE-2013-4154
The qemuAgentCommand function in libvirt before 1.1.1, when a guest agent is not configured, allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via vectors related to "agent based cpu (un)plug," as demonstrated by the "virsh vcpucount foobar --guest" command. La función qemuAgentCommand en libvirt anteriores a 1.1.1, cuando no es configurado un agente invitado, permite a atacantes remotos causar una denegación de servicio (referencia a puntero nulo y cuelgue) a través de vectores relacionados con "agent based cpu (un)plug", como fue demostrado por el comando "virsh vcpucount foobar --guest". • http://libvirt.org/git/?p=libvirt.git%3Ba=commitdiff%3Bh=96518d4316b711c72205117f8d5c967d5127bbb6 http://libvirt.org/news.html http://openwall.com/lists/oss-security/2013/07/19/12 https://bugzilla.redhat.com/show_bug.cgi?id=984821 https://bugzilla.redhat.com/show_bug.cgi?id=986386 •
