The eepro100 emulator in QEMU qemu-kvm blank allows local guest users to cause a denial of service (application crash and infinite loop) via vectors involving the command block list. El emulador de eepro100 en qemu-kvm de QEMU permite a los usuarios huéspedes locales provocar una denegación de servicio (fallo de la aplicación y bucle infinito) a través de vectores que implican la lista de bloqueo de comandos. • 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/2015/11/25/11 http://www.securityfocus.com/bid/77985 https://lists.gnu.org/archive/html/qemu-devel/2015-10/msg03911.html https://security.gentoo.org/glsa/201602-01 • CWE-399: Resource Management Errors •
CVSS: 8.8EPSS: 0%CPEs: 7EXPL: 0CVE-2015-7504 – Qemu: net: pcnet: heap overflow vulnerability in pcnet_receive
https://notcve.org/view.php?id=CVE-2015-7504
Heap-based buffer overflow in the pcnet_receive function in hw/net/pcnet.c in QEMU allows guest OS administrators to cause a denial of service (instance crash) or possibly execute arbitrary code via a series of packets in loopback mode. Desbordamiento de búfer basado en memoria dinámica (heap) en la función pcnet_receive en hw/net/pcnet.c en QEMU permite que administradores del sistema operativo invitados provoquen una denegación de servicio (cierre inesperado de la instancia) o que puedan ejecutar código arbitrario mediante una serie de paquetes en modo de bucle invertido. A heap-based buffer overflow flaw was discovered in the way QEMU's AMD PC-Net II Ethernet Controller emulation received certain packets in loopback mode. A privileged user (with the CAP_SYS_RAWIO capability) inside a guest could use this flaw to crash the host QEMU process (resulting in denial of service) or, potentially, execute arbitrary code with privileges of the host QEMU process. • http://rhn.redhat.com/errata/RHSA-2015-2694.html http://rhn.redhat.com/errata/RHSA-2015-2695.html http://rhn.redhat.com/errata/RHSA-2015-2696.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/2015/11/30/2 http://www.securityfocus.com/bid/78227 http://www.securitytracker.com/id/1034268 http://xenbits.xen.org/xsa/advisory • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2015-7512
Buffer overflow in the pcnet_receive function in hw/net/pcnet.c in QEMU, when a guest NIC has a larger MTU, allows remote attackers to cause a denial of service (guest OS crash) or execute arbitrary code via a large packet. Desbordamiento de buffer en la función pcnet_receive en hw/net/pcnet.c en QEMU, cuando un NIC invitado tiene un MTU más grande, permite a atacantes provocar una denegación de servicio (caída de SO invitado) o ejecutar código arbitrario a través de un paquete grande. A buffer overflow flaw was found in the way QEMU's AMD PC-Net II emulation validated certain received packets from a remote host in non-loopback mode. A remote, unprivileged attacker could potentially use this flaw to execute arbitrary code on the host with the privileges of the QEMU process. Note that to exploit this flaw, the guest network interface must have a large MTU limit. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=8b98a2f07175d46c3f7217639bd5e03f http://rhn.redhat.com/errata/RHSA-2015-2694.html http://rhn.redhat.com/errata/RHSA-2015-2695.html http://rhn.redhat.com/errata/RHSA-2015-2696.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/2015/11/30/3 http://www.oracle.com/technetwork/topics/securi • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-122: Heap-based Buffer Overflow •

Integer overflow in the VNC display driver in QEMU before 2.1.0 allows attachers to cause a denial of service (process crash) via a CLIENT_CUT_TEXT message, which triggers an infinite loop. Un desbordamiento de enteros en el controlador de pantalla VNC en QEMU versiones anteriores a 2.1.0, permite a atacantes causar una denegación de servicio (bloqueo del proceso) mediante un mensaje CLIENT_CUT_TEXT, que desencadena un bucle infinito. • http://lists.fedoraproject.org/pipermail/package-announce/2015-October/168077.html http://lists.fedoraproject.org/pipermail/package-announce/2015-October/168646.html http://lists.fedoraproject.org/pipermail/package-announce/2015-October/168671.html http://lists.opensuse.org/opensuse-security-announce/2015-10/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2015-11/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2015-11/msg00011.html http://www.openwall.com/lists/oss-security&#x • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
