Descriptions

Integer overflow in hw/virtio/virtio-crypto.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (QEMU process crash) or possibly execute arbitrary code on the host via a crafted virtio-crypto request, which triggers a heap-based buffer overflow.

Desbordamiento de entero en hw/virtio/virtio-crypto.c en QEMU (también conocido como Quick Emulator) permite a usuarios locales privilegiados del SO invitado provocar una denegación de servicio (caída del proceso QEMU) o posiblemente ejecutar código arbitrario en el host a través de una solicitud virtio-crypto manipulada, lo que desencadena un desbordamiento de búfer basado en memoria dinámica.

Multiple vulnerabilities have been found in QEMU, the worst of which could lead to the execution of arbitrary code on the host system. Versions less than 2.8.0-r1 are affected.
