Qemu, when built with VNC display driver support, allows remote attackers to cause a denial of service (arithmetic exception and application crash) via crafted SetPixelFormat messages from a client. Qemu, cuando se construye con soporte de controlador de pantalla VNC, permite a atacantes remotos provocar una denegación de servicio (excepción aritmética y caída de aplicación) a través de mensajes SetPixelFormat manipulados desde un cliente. • http://git.qemu-project.org/?p=qemu.git%3Ba=commitdiff%3Bh=4c65fed8bdf96780735dbdb92a8 http://www.debian.org/security/2016/dsa-3469 http://www.debian.org/security/2016/dsa-3470 http://www.debian.org/security/2016/dsa-3471 http://www.openwall.com/lists/oss-security/2015/12/08/7 http://www.securityfocus.com/bid/78708 https://bugzilla.redhat.com/show_bug.cgi?id=1289541 https://security.gentoo.org/glsa/201602-01 • CWE-369: Divide By Zero •
CVE-2015-8744
https://notcve.org/view.php?id=CVE-2015-8744
QEMU (aka Quick Emulator) built with a VMWARE VMXNET3 paravirtual NIC emulator support is vulnerable to crash issue. It occurs when a guest sends a Layer-2 packet smaller than 22 bytes. A privileged (CAP_SYS_RAWIO) guest user could use this flaw to crash the QEMU process instance resulting in DoS. QEMU (también conocido como Quick Emulator) construido con un soporte de emulador VMWARE VMXNET3 paravirtual NIC es vulnerable a un problema de caída. Ocurre cuando un invitado envía un paquete Layer-2 más pequeño que 22 bytes. • http://git.qemu.org/?p=qemu.git%3Ba=commitdiff%3Bh=a7278b36fcab9af469563bd7b http://www.debian.org/security/2016/dsa-3471 http://www.openwall.com/lists/oss-security/2016/01/04/3 http://www.openwall.com/lists/oss-security/2016/01/04/6 http://www.securityfocus.com/bid/79821 http://www.securitytracker.com/id/1034576 https://bugzilla.redhat.com/show_bug.cgi?id=1270871 https://security.gentoo.org/glsa/201602-01 • CWE-20: Improper Input Validation •
CVE-2016-1981 – Qemu: net: e1000 infinite loop in start_xmit and e1000_receive_iov routines
https://notcve.org/view.php?id=CVE-2016-1981
QEMU (aka Quick Emulator) built with the e1000 NIC emulation support is vulnerable to an infinite loop issue. It could occur while processing data via transmit or receive descriptors, provided the initial receive/transmit descriptor head (TDH/RDH) is set outside the allocated descriptor buffer. A privileged user inside guest could use this flaw to crash the QEMU instance resulting in DoS. QEMU (también conocido como Quick Emulator) construido con el soporte de emulación e1000 NIC es vulnerable a un problema de bucle infinito. Podría ocurrir mientras se procesan datos a través de descriptores de transmisión o recepción, siempre que la cabeza inicial del descriptor de recepción/transmisión (TDH/RDH) se establezca fuera del búfer de descriptor asignado. • http://rhn.redhat.com/errata/RHSA-2016-2585.html http://www.debian.org/security/2016/dsa-3469 http://www.debian.org/security/2016/dsa-3470 http://www.debian.org/security/2016/dsa-3471 http://www.openwall.com/lists/oss-security/2016/01/19/10 http://www.openwall.com/lists/oss-security/2016/01/22/1 http://www.securityfocus.com/bid/81549 https://bugzilla.redhat.com/show_bug.cgi?id=1298570 https://lists.gnu.org/archive/html/qemu-devel/2016-01/msg03454.html • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
