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)

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.
