The package spice before version 0.12.6-1 is vulnerable to multiple
issues, including denial of service and privilege escalation.
Upgrade to 0.12.6-1.
# pacman -Syu "spice>=0.12.6-1"

- CVE-2015-3247 (race condition flaw):
A race condition flaw was found in spice's
worker_update_monitors_config() function, leading to a heap-based memory
corruption. A user in a guest could leverage this flaw to crash the host
QEMU-KVM process or, possibly, execute arbitrary code with the
privileges of the host QEMU-KVM process.
- CVE-2015-5260 (heap-based buffer overflow):
A heap-based buffer overflow flaw was found in the way spice handled
certain QXL commands related to the "surface_id" parameter. A user in a
guest could use this flaw to crash the host QEMU-KVM process or,
possibly, execute arbitrary code with the privileges of the host
- CVE-2015-5261 (heap-based buffer overflow):
A heap-based buffer overflow flaw was found in the way SPICE handled
certain guest QXL commands related to surface creation. A user in a
guest could use this flaw to read and write arbitrary memory locations
on the host.
A rogue guest user can cause a denial of service to the host or execute
arbitrary command with the privileges of the host QEMU-KVM process.
