Fedora Update Notification
FEDORA-2017-828f8a8fc6
2018-01-02 14:45:21.623235
——————————————————————————–

Name : glibc
Product : Fedora 27
Version : 2.26
Release : 21.fc27
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 RHBZ#1468837, which caused bash to lack job control in
mock chroots. (Note that glibc inside the chroot needs to be upgraded for the
fix to be effective.) In additon, two dynamic linker issues where fixed which
are not security bugs, but received CVE IDs nevertheless (RHBZ#1524867,
CVE-2017-1000408, CVE-2017-1000409).
