CVSS: 7.2EPSS: 0%CPEs: 13EXPL: 0CVE-2015-5154 – qemu: ide: atapi: heap overflow during I/O buffer memory access
https://notcve.org/view.php?id=CVE-2015-5154
Heap-based buffer overflow in the IDE subsystem in QEMU, as used in Xen 4.5.x and earlier, when the container has a CDROM drive enabled, allows local guest users to execute arbitrary code on the host via unspecified ATAPI commands. Desbordamiento del buffer basado en memoria dinámica en el subsistema IDE en QEMU, usado en Xen 4.5.x y versiones anteriores, cuando el contenedor tiene una unidad CDROM habilitada, permite a usuarios invitados locales ejecutar código arbitrario en el host a través de comandos ATAPI no especificados. A heap buffer overflow flaw was found in the way QEMU's IDE subsystem handled I/O buffer access while processing certain ATAPI commands. A privileged guest user in a guest with the CDROM drive enabled could potentially use this flaw to execute arbitrary code on the host with the privileges of the host's QEMU process corresponding to the guest. • http://lists.fedoraproject.org/pipermail/package-announce/2015-August/163472.html http://lists.fedoraproject.org/pipermail/package-announce/2015-August/163658.html http://lists.fedoraproject.org/pipermail/package-announce/2015-August/163681.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00042.html http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00017.html http://lists.opensuse.org/opensuse-security-annou • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

GNTTABOP_swap_grant_ref in Xen 4.2 through 4.5 does not check the grant table operation version, which allows local guest domains to cause a denial of service (NULL pointer dereference) via a hypercall without a GNTTABOP_setup_table or GNTTABOP_set_version. GNTTABOP_swap_grant_ref en Xen 4.2 hasta 4.5 no comprueba la versión de la operación de ceder tablas, lo que permite a dominios locales invitados causar una denegación de servicio (referencia a puntero nulo) a través de una hiperllamada sin GNTTABOP_setup_table o GNTTABOP_set_version. • http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00030.html http://support.citrix.com/article/CTX201145 http://www.debian.org/security/2015/dsa-3286 http://www.securityfocus.com/bid/75141 http://www.securitytracker.com/id/1032568 http://xenbits.xen.org/xsa/advisory-134.html https://security.gentoo.org/glsa/201604-03 https: •

The compat_iret function in Xen 3.1 through 4.5 iterates the wrong way through a loop, which allows local 32-bit PV guest administrators to cause a denial of service (large loop and system hang) via a hypercall_iret call with EFLAGS.VM set. La función compat_iret en Xen 3.1 hasta 4.5 itera en la dirección errónea a través de un bucle, lo que permite a administradores locales invitados de PV de 32 dits causar una denegación de servicio (bucle grande y cuelgue del sistema) a través de una llamada hypercall_iret con el juego EFLAGS.VM. • http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00029.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00030.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00014.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00027.html http://support.citrix.com/article/CTX201145 http://www. • CWE-399: Resource Management Errors •

Xen 3.3.x through 4.5.x enables logging for PCI MSI-X pass-through error messages, which allows local x86 HVM guests to cause a denial of service (host disk consumption) via certain invalid operations. Xen 3.3.x hasta 4.5.x habilita el registro para mensajes de error 'pass-through' de PCI MSI-X, lo que permite a invitados locales de x86 HVM causar una denegación de servicio (consumo de disco de anfitrión) a través de ciertas operaciones inválidas. • http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160154.html http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160171.html http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160685.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00029.html http://lists.opensuse.org/opensuse-security-announce&#x • CWE-399: Resource Management Errors •
