This update for glibc fixes the following issues :
A privilege escalation bug in the realpath() function has been fixed. [CVE-2018-1000001, bsc#1074293]
A buffer manipulation vulnerability in nscd has been fixed that could possibly have lead to an nscd daemon crash or code execution as the user running nscd.
[CVE-2014-9984, bsc#1043984]
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.
