CVE-2016-0749: Buffer Overflow
First published: Thu Jun 09 2016(Updated: )
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.
