https://notcve.org/view.php?id=CVE-2013-2007
The qemu guest agent in Qemu 1.4.1 and earlier, as used by Xen, when started in daemon mode, uses weak permissions for certain files, which allows local users to read and write to these files. El agente qemu en en Qemu 1.4.1 y anteriores, usado por Xen, cuando se inicia en modo demonio, utiliza permisos débiles para determinados archivos, lo que permite a usuarios locales leer y escribir sobre estos archivos. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=c689b4f1bac352dcfd6ecb9a1d45337de0f1de67 http://lists.opensuse.org/opensuse-updates/2013-07/msg00057.html http://osvdb.org/93032 http://rhn.redhat.com/errata/RHSA-2013-0791.html http://rhn.redhat.com/errata/RHSA-2013-0896.html http://secunia.com/advisories/53325 http://www.openwall.com/lists/oss-security/2013/05/06/5 http://www.securityfocus.com/bid/59675 http://www.securitytracker.com/id/1028521 https://bugzilla.redhat.com/ • CWE-264: Permissions, Privileges, and Access Controls •

Buffer overflow in the e1000_receive function in the e1000 device driver (hw/e1000.c) in QEMU 1.3.0-rc2 and other versions, when the SBP and LPE flags are disabled, allows remote attackers to cause a denial of service (guest OS crash) and possibly execute arbitrary guest code via a large packet.

https://notcve.org/view.php?id=CVE-2012-3515
Qemu, as used in Xen 4.0, 4.1 and possibly other products, when emulating certain devices with a virtual console backend, allows local OS guest users to gain privileges via a crafted escape VT100 sequence that triggers the overwrite of a "device model's address space." Qemu, tal como se utiliza en Xen v4.0, v4.1 y posiblemente otros productos, al emular ciertos dispositivos con una consola virtual, permite a los usuarios locales del SO invitado obtener privilegios a través de una secuencia VT100 de escape manipulada que desencadena la sobrescritura del espacio de direcciones de un "device model's address space." • http://git.qemu.org/?p=qemu-stable-0.15.git%3Ba=log http://lists.opensuse.org/opensuse-security-announce/2012-09/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2012-09/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2012-09/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2012-09/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2012-09/msg00012.html http://lists.opensuse.org/opensuse-security-announce/2012-09/msg00016.ht • CWE-20: Improper Input Validation CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
