Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2015-5239 low priority: Ubuntu including 2 source packages (qemu, qemu-kvm), 8 status rows across 4 suites (precise, trusty, upstream, vivid): DNE 3, needs-triage 2, released 2, not-affected 1.
Integer overflow in the VNC display driver in QEMU before 2.1.0 allows attachers to cause a denial of service (process crash) via a CLIENT_CUT_TEXT message, which triggers an infinite loop.
