Security issue fixed :

CVE-2017-15671: Fixed memory leak in glob with GLOB_TILDE
(bsc#1064569, BZ #22325).

Non-security issue fixed: Avoid access beyond memory bounds in
pthread_attr_getaffinity_np (bsc#1110170, BZ #15618).

Remove improper assert in dlclose (bsc#1110174, BZ #11941).

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."
