This update for glibc fixes the following issues :
CVE-2017-1000366: Fix a potential privilege escalation vulnerability that allowed unprivileged system users to manipulate the stack of setuid binaries to gain special privileges. [bsc#1039357]
The incorrectly defined constant O_TMPFILE has been fixed. [bsc#1038690]
A defect in glibc’s regression test suite has been remedied to avoid false positives. [bsc#987216]
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.
