Fedora 27: 2017-828f8a8fc6 Moderate: Glibc Job Control Issue Fix

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.

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).
