Fedora 26: glibc Security Update
Summary
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 improves compatibility with legacy 32-bit i386 applications
(RHBZ#1471427) and addresses a minor security vulnerability in the DNS stub
resolver (CVE-2017-12132).
