** Description changed:

- Incomplete fix for CVE-2014-8480
+ The instruction decoder in arch/x86/kvm/emulate.c in the KVM subsystem in
+ the Linux kernel before 3.18-rc2 does not properly handle invalid
+ instructions, which allows guest OS users to cause a denial of service
+ (NULL pointer dereference and host OS crash) via a crafted application that
+ triggers (1) an improperly fetched instruction or (2) an instruction that
+ occupies too many bytes. NOTE: this vulnerability exists because of an
+ incomplete fix for CVE-2014-8480.
