Fedora Update Notification
FEDORA-2017-2c63df4fe3

--------------------------------------------------------------------------------

Name        : glibc
Product     : Fedora 26
Version     : 2.25
Release     : 12.fc26
URL         : http://www.gnu.org/software/glibc/
Summary     : The GNU libc libraries
Description :
The glibc package contains standard libraries which are used by
multiple programs on the system. In order to save disk space and
memory, as well as to make upgrading easier, common system code is
kept in one place and shared between programs. This particular package
contains the most important sets of shared libraries: the standard C
library and the standard math library. Without these two libraries, a
Linux system will not function.

--------------------------------------------------------------------------------
Update Information:

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).
