INSTALLING THE UPDATES

6, and Scientific Linux 6 install these updates.
On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,

DESCRIPTION
* CVE-2014-3185: Memory corruption in USB serial WhiteHEAD device driver.
The USB ConnectTech WhiteHEAT serial driver is vulnerable to a memory
corruption flaw. It could occur when reading completion commands via USB
Request Blocks buffers.
A local user with physical access to the system could use this flaw to
corrupt kernel memory area or crash the system kernel resulting in a
denial-of-service.
* CVE-2014-3645 and CVE-2014-3646: KVM guest denial-of-service when using invalid opcodes.
The KVM host emulator does not gracefully handle a KVM guest using the
invept or invvpid opcodes, causing a guest VM exit without proper error
codes being propagated to userspace. A local, unprivileged guest user
could use this flaw to crash a KVM guest VM and cause a denial-of-service.
* CVE-2014-3611: Denial-of-service in KVM emulated programmable interval timer.
Incorrect locking in the KVM emulated programmable interval timer (PIT)
could crash the host kernel under specific conditions. A local attacker
could use this flaw to cause a denial-of-service in the host KVM.
