"This update for kvm fixes the following issues :

Security issues fixed :

  - CVE-2015-7512: The receive packet size is now checked in
    the emulated pcnet driver, eliminating buffer overflow
    and potential security issue by malicious guest systems.
    (bsc#957162)

  - CVE-2015-8345: A infinite loop in processing command
    block list was fixed that could be exploit by malicious
    guest systems (bsc#956829).

Other bugs fixed :

  - To assist users past the migration incompatibility
    discussed in bsc#950590 (restore migration compatibility
    with SLE11 SP3 and SLE12, at the unfortunate expense to
    prior SLE11 SP4 kvm release compatability when a
    virtio-net device is used), print a message which
    references the support document TID 7017048. See
    https://www.suse.com/support/kb/doc.php?id=7017048

  - Fix cases of wrong clock values in kvmclock timekeeping
    (bsc#947164 and bsc#953187)

  - Enforce pxe rom sizes to ensure migration compatibility.
    (bsc#950590)

  - Fix kvm live migration fails between sles11 sp3 and sp4
    (bsc#950590)

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."
