Doc Text:
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.

Description Stefan Cornelius 2016-01-21 10:59:27 UTC 
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 via spice could possibly exploit this flaw to crash the QEMU-KVM process, or, possibly, execute arbitrary code with the privileges of the host QEMU-KVM process.

The RHEL7.3 bug is bug#1287969, the RHEL6 one is bug#1297786. Should they block this bug too?
