SUSE SLED12 / SLES12 Security Update : kdump (SUSE-SU-2016:2553-1)

This script is Copyright (C) 2016-2017 Tenable Network Security, Inc.


Synopsis :

The remote SUSE host is missing one or more security updates.

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)
