The is_rndis function in the USB Net device emulator (hw/usb/dev-network.c) in QEMU before 2.5.1 does not properly validate USB configuration descriptor objects, which allows local guest OS administrators to cause a denial of service (NULL pointer dereference and QEMU process crash) via vectors involving a remote NDIS control message packet. La función is_rndis en el dispositivo de emulación USB Net (hw/usb/dev-network.c) en QEMU en versiones anteriores a 2.5.1 no valida correctamente objetos descriptores de configuración USB, lo que permite a administradores locales del SO invitado provocar una denegación de servicio (referencia a puntero NULL y caída del proceso QEMU) a través de vectores que involucran un paquete de mensajes de control remoto de NDIS. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=80eecda8e5d09c442c24307f340840a5b70ea3b9 http://lists.nongnu.org/archive/html/qemu-stable/2016-03/msg00064.html http://www.openwall.com/lists/oss-security/2016/02/16/7 http://www.securityfocus.com/bid/83274 http://www.ubuntu.com/usn/USN-2974-1 https://bugzilla.redhat.com/show_bug.cgi?id=1302299 https://lists.debian.org/debian-lts-announce/2018/11/msg00038.html https://lists.gnu.org/archive/html/qemu-devel/2016-02/msg02553.h •

QEMU (aka Quick Emulator) built with the Rocker switch emulation support is vulnerable to an off-by-one error. It happens while processing transmit (tx) descriptors in 'tx_consume' routine, if a descriptor was to have more than allowed (ROCKER_TX_FRAGS_MAX=16) fragments. A privileged user inside guest could use this flaw to cause memory leakage on the host or crash the QEMU process instance resulting in DoS issue. QEMU (también conocido como Quick Emulator) construido con el soporte de emulación switch Rocker es vulnerable a un error off-by-one. Sucede mientras se procesan los descriptores de transmisión (tx) en rutina 'tx_consume', si un descriptor debía tener más fragmentos (ROCKER_TX_FRAGS_MAX=16) de los permitidos. • http://www.openwall.com/lists/oss-security/2015/12/28/6 http://www.openwall.com/lists/oss-security/2015/12/29/1 http://www.securityfocus.com/bid/79706 https://bugzilla.redhat.com/show_bug.cgi?id=1286971 https://lists.gnu.org/archive/html/qemu-devel/2015-12/msg04629.html https://security.gentoo.org/glsa/201602-01 • CWE-193: Off-by-one Error •

QEMU (aka Quick Emulator) built with the TPR optimization for 32-bit Windows guests support is vulnerable to a null pointer dereference flaw. It occurs while doing I/O port write operations via hmp interface. In that, 'current_cpu' remains null, which leads to the null pointer dereference. A user or process could use this flaw to crash the QEMU instance, resulting in DoS issue. QEMU (también conocido como Quick Emulator) construido con el soporte de invitados TPR optimization for 32-bit Windows es vulnerable a una falla de referencia puntero null. • 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/2016/01/16/1 http://www.openwall.com/lists/oss-security/2016/01/16/6 http://www.securityfocus.com/bid/81058 https://bugzilla.redhat.com/show_bug.cgi?id=1283934 https://lists.gnu.org/archive/html/qemu-devel/2016-01/msg02812.html https://security.gentoo.org/glsa/201604-01 • CWE-476: NULL Pointer Dereference •
