CVE-2016-0749
QEMU-KVM Smartcard Heap-Based Buffer Overflow Denial of Service
Description

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.

    Changed Description 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. 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.
