On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,

DESCRIPTION

* CVE-2014-8369: Denial-of-service in KVM page mapping.

Due to an incomplete fix for CVE-2014-3601, the KVM map pages function
miscalculates the number of pages to be un-pinned in case of a mapping
failure, which allows guest OS users to cause a denial-of-service by
corrupting the host memory.


* CVE-2014-7842: Denial of service in KVM L1 guest from L2 guest.

A malicious nested L2 KVM guest can cause the L1 guest to crash by
triggering a race condition when accessing MMIO memory. A local attacker
could use this flaw to cause a denial of service.
