Descriptions
The smartcard interaction in SPICE allows remote attackers to cause a denial of service (QEMU-KVM process crash) or possibly execute arbitrary code via vectors related to connecting to a guest VM, which triggers a heap-based buffer overflow.
La interacción smartcard en SPICE permite a atacantes remotos provocar un denegación de servicio (caída del proceso QEMU-KVM) o ejecutar, posiblemente, un código arbitrario a través de véctores relacionados con conectarse con un invitado VM, lo que ejecuta un desbordamiento de bufer basado en memoria dinámica.
A memory allocation flaw, leading to a heap-based buffer overflow, was found in spice's smartcard interaction, which runs under the QEMU-KVM context on the host. A user connecting to a guest VM using spice could potentially use this flaw to crash the QEMU-KVM process or execute arbitrary code with the privileges of the host's QEMU-KVM process.
