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 •

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 does not properly restrict write access to the host MSI message data field, which allows local x86 HVM guest administrators to cause a denial of service (host interrupt handling confusion) via vectors related to qemu and accessing spanning multiple fields. Xen 3.3.x hasta la versión 4.5.x no restringe correctamente el acceso a escritura al campo de datos del mensaje MSI del host, lo que permite a administradores invitados x86 HVM locales causar una denegación de servicio (confusión en el manejo de interrupción de host) a través de vectores relacionados con qemu y accediendo a múltiples campos de expansión. • 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-264: Permissions, Privileges, and Access Controls •
