spice (SL7)

Synopsis: Important: spice security update
Advisory ID: SLSA-2016:1205-1
Issue Date: 2016-06-06
CVE Numbers: CVE-2016-0749

Security Fix(es):

* 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.

* A memory access flaw was found in the way spice handled certain guests
using crafted primary surface parameters. A user in a guest could use this
flaw to read from and write to arbitrary memory locations on the host.
