CVE-2013-2007 – qemu: guest agent creates files with insecure permissions in deamon mode

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 •

CVE-2012-6075 – qemu: e1000 driver buffer overflow when processing large packets when SBP and LPE flags are disabled

https://notcve.org/view.php?id=CVE-2012-6075

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. Desbordamiento de buffer en la función e1000_receive del controlador de dispositivo e1000 (hw/e1000.c) en QEMU v1.3.0-rc2 y otras versiones, cuando las banderas de PAS y LPE están deshabilitadas, permiten ataques remotos que provocan una denegación de servicios (errores en el sistema operativo invitado) y posiblemente ejecutar código arbitrario. • http://git.qemu.org/?p=qemu.git%3Ba=commitdiff%3Bh=b0d9ffcd0251161c7c92f94804dcf599dfa3edeb http://lists.fedoraproject.org/pipermail/package-announce/2013-January/097541.html http://lists.fedoraproject.org/pipermail/package-announce/2013-January/097575.html http://lists.fedoraproject.org/pipermail/package-announce/2013-January/097705.html http://lists.nongnu.org/archive/html/qemu-devel/2012-12/msg00533.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00021.html http://lists.opensuse.org/opensuse • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

CVE-2012-3515 – qemu: VT100 emulation vulnerability

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 •
