   An update that solves one vulnerability and has 13 fixes is
   now available.

Description:


   This update for kdump provides several fixes and enhancements:

   - Refresh kdumprd if /etc/hosts or /etc/nsswitch.conf is changed.
     (bsc#943214)
   - Add a separate systemd service to rebuild kdumprd at boot. (bsc#943214)
   - Improve network setup in the kdump environment by reading configuration
     from wicked by default (system configuration files are used as a
     fallback). (bsc#980328)
   - Use the last mount entry in kdump_get_mountpoints(). (bsc#951844)
   - Remove 'notsc' from the kdump kernel command line. (bsc#973213)
   - Handle dump files with many program headers. (bsc#932339, bsc#970708)
   - Fall back to stat() if file type is DT_UNKNOWN. (bsc#964206)
   - Remove vm. sysctls from kdump initrd. (bsc#927451, bsc#987862)
   - Use the exit code of kexec, not that of "local". (bsc#984799)
   - Convert sysroot to a bind mount in kdump initrd. (bsc#976864)
   - Distinguish between Xenlinux (aka Xenified or SUSE) and pvops Xen
     kernels, as the latter can run on bare metal. (bsc#974270)
   - CVE-2016-5759: Use full path to dracut as argument to bash. (bsc#989972,
     bsc#990200)
