"The SUSE Linux Enterprise Server 12 kernel was updated to 3.12.39 to
receive various security and bugfixes.

Following security bugs were fixed :

  - CVE-2015-0777: The XEN usb backend could leak
    information to the guest system due to copying
    uninitialized memory.

  - CVE-2015-2150: Xen and the Linux kernel did not properly
    restrict access to PCI command registers, which might
    have allowed local guest users to cause a denial of
    service (non-maskable interrupt and host crash) by
    disabling the (1) memory or (2) I/O decoding for a PCI
    Express device and then accessing the device, which
    triggers an Unsupported Request (UR) response.

The update package also includes non-security fixes. See advisory for
details.

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
