The remote Scientific Linux host is missing one or more security
This update fixes the following security issues :
- A flaw was found in the way KVM (Kernel-based Virtual
Machine) initialized a guest's registered pv_eoi
(paravirtualized end-of-interrupt) indication flag when
entering the guest. An unprivileged guest user could
potentially use this flaw to crash the host.
- A missing sanity check was found in the
kvm_set_memory_region() function in KVM, allowing a
user-space process to register memory regions pointing
to the kernel address space. A local, unprivileged user
could use this flaw to escalate their privileges.
- A double free flaw was found in the Linux kernel's
Virtual Ethernet Tunnel driver (veth). A remote attacker
could possibly use this flaw to crash a target system.
The system must be rebooted for this update to take effect.
