CVSS: 5.0EPSS: 3%CPEs: 9EXPL: 0CVE-2014-3657 – libvirt: domain_conf: domain deadlock DoS
https://notcve.org/view.php?id=CVE-2014-3657
The virDomainListPopulate function in conf/domain_conf.c in libvirt before 1.2.9 does not clean up the lock on the list of domains, which allows remote attackers to cause a denial of service (deadlock) via a NULL value in the second parameter in the virConnectListAllDomains API command. La función virDomainListPopulate en conf/domain_conf.c en libvirt anterior a 1.2.9 no limpia el bloqueo en la lista de dominios, lo que permite a atacantes remotos causar una denegación de servicio (bloqueo mutuo) a través de un valor nulo en el parámetro second en el comando de API virConnectListAllDomains. A denial of service flaw was found in the way libvirt's virConnectListAllDomains() function computed the number of used domains. A remote attacker able to establish a read-only connection to libvirtd could use this flaw to make any domain operations within libvirt unresponsive. • http://libvirt.org/git/?p=libvirt.git%3Ba=commitdiff%3Bh=fc22b2e74890873848b43fffae43025d22053669 http://lists.opensuse.org/opensuse-updates/2014-10/msg00014.html http://lists.opensuse.org/opensuse-updates/2014-10/msg00017.html http://rhn.redhat.com/errata/RHSA-2014-1352.html http://secunia.com/advisories/60291 http://secunia.com/advisories/62303 http://security.libvirt.org/2014/0005.html http://www.ubuntu.com/usn/USN-2404-1 https://access.redhat.com/security/cve/CVE-2014-3657 https&# • CWE-20: Improper Input Validation CWE-399: Resource Management Errors •
CVSS: 5.8EPSS: 3%CPEs: 12EXPL: 0CVE-2014-3633 – libvirt: qemu: out-of-bounds read access in qemuDomainGetBlockIoTune() due to invalid index
https://notcve.org/view.php?id=CVE-2014-3633
The qemuDomainGetBlockIoTune function in qemu/qemu_driver.c in libvirt before 1.2.9, when a disk has been hot-plugged or removed from the live image, allows remote attackers to cause a denial of service (crash) or read sensitive heap information via a crafted blkiotune query, which triggers an out-of-bounds read. La función qemuDomainGetBlockIoTune en qemu/qemu_driver.c en libvirt anterior a 1.2.9, cuando un disco ha sido conectado en caliente o eliminado de la imagen en vivo, permite a atacantes remotos causar una denegación de servicio (caída) o leer información sensible de la memoria dinámica a través de una consulta blkiotune manipulada, lo que provoca una lectura fuera de rango. An out-of-bounds read flaw was found in the way libvirt's qemuDomainGetBlockIoTune() function looked up the disk index in a non-persistent (live) disk configuration while a persistent disk configuration was being indexed. A remote attacker able to establish a read-only connection to libvirtd could use this flaw to crash libvirtd or, potentially, leak memory from the libvirtd process. • http://libvirt.org/git/?p=libvirt.git%3Ba=commitdiff%3Bh=3e745e8f775dfe6f64f18b5c2fe4791b35d3546b http://lists.opensuse.org/opensuse-updates/2014-10/msg00014.html http://lists.opensuse.org/opensuse-updates/2014-10/msg00017.html http://rhn.redhat.com/errata/RHSA-2014-1352.html http://secunia.com/advisories/60291 http://secunia.com/advisories/60895 http://security.gentoo.org/glsa/glsa-201412-04.xml http://security.libvirt.org/2014/0004.html http://www.debian.org/security/2014/dsa-3038 h • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •

The qemuMigrationWaitForSpice function in qemu/qemu_migration.c in libvirt before 1.1.3 does not properly enter a monitor when performing seamless SPICE migration, which allows local users to cause a denial of service (NULL pointer dereference and libvirtd crash) by causing domblkstat to be called at the same time as the qemuMonitorGetSpiceMigrationStatus function. La función qemuMigrationWaitForSpice en qemu/qemu_migration.c en libvirt anterior a 1.1.3 no entra debidamente en un monitor cuando realiza migración SPICE ininterrumpida, lo que permite a usuarios locales causar una denegación de servicio (referencia a puntero nulo y caída de libvirtd) al provocar que domblkstat sea llamado en el mismo momento que la función qemuMonitorGetSpiceMigrationStatus. • http://libvirt.org/git/?p=libvirt.git%3Ba=commit%3Bh=484cc321 http://libvirt.org/news.html http://lists.opensuse.org/opensuse-updates/2014-05/msg00004.html http://secunia.com/advisories/60895 http://security.gentoo.org/glsa/glsa-201412-04.xml http://www.openwall.com/lists/oss-security/2014/03/18/1 http://www.openwall.com/lists/oss-security/2014/03/18/3 https://bugzilla.redhat.com/show_bug.cgi?id=1077620 •

The libxlDomainGetNumaParameters function in the libxl driver (libxl/libxl_driver.c) in libvirt before 1.2.1 does not properly initialize the nodemap, which allows local users to cause a denial of service (invalid free operation and crash) or possibly execute arbitrary code via an inactive domain to the virsh numatune command. La función libxlDomainGetNumaParameters en el driver libxl (libxl/libxl_driver.c) de libvirt anteriores a 1.2.1 no inicializa correctamente el nodemap, lo cual permite a usuarios locales causar denegación de servicio (operación de liberación inválida y caída) o posiblemente ejecutar código arbitrario a través de un dominio inactivo en el comando virsh numatune. • http://libvirt.org/news.html http://lists.opensuse.org/opensuse-updates/2014-02/msg00060.html http://secunia.com/advisories/60895 http://security.gentoo.org/glsa/glsa-201412-04.xml http://www.ubuntu.com/usn/USN-2093-1 https://bugzilla.redhat.com/show_bug.cgi?id=1048629 https://www.redhat.com/archives/libvir-list/2013-December/msg01176.html https://www.redhat.com/archives/libvir-list/2013-December/msg01258.html • CWE-264: Permissions, Privileges, and Access Controls •

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') •
