DESCRIPTION

* Improved fix to CVE-2015-2150: Denial-of-service in Xen PCI passthrough devices.

Incorrect restrictions to PCI device configuration could allow a
privileged user in a Xen guest to trigger a fatal NMI in the host.  A
privileged, local user could use this flaw to cause a denial-of-service.


* CVE-2015-3331: Denial-of-service in Intel AES RFC4106 decryption.

Incorrect mapping of buffers in the Intel AES RFC4106 implementation
could result in a kernel crash.  A local, unprivileged user with access
to AF_ALG(aead) sockets could use this flaw to trigger a
denial-of-service.
