"This update addresses various minor issues in the glibc package :

  - The DNS stub resolver now picks up changes to
    `/etc/resolv.conf` automatically (RHBZ#1374239).

  - The DNS stub resolver supports an unlimited number of
    search domains (RHBZ#168253).

  - CVE-2015-5180, a segmentation fault potentially
    affecting applications which use the DNS stub resolver
    in an unusual way, has been fixed (RHBZ#1251403).

  - `/var/db/Makefile` is now shipped in the `nss_db`
    package (RHBZ#1498900).

  - The IBM858 character set is now supported
    (RHBZ#1416405).

  - The `compat` NSS service module is again part of the
    main glibc package (RHBZ#1400538).

  - A pointer alignment/endianess issue was fixed in the NSS
    group merging implementation (RHBZ#1471985).

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as
possible without introducing additional issues."
