  - Enforce receive packet size, thus eliminating buffer
    overflow and potential security issue. (bsc#957162
    CVE-2015-7512)

  - Infinite loop in processing command block list.
    CVE-2015-8345 (bsc#956829) :

Also a non-security bug fixed :

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

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."
