Fedora Update Notification
FEDORA-2017-fb5e227432
2017-12-19 18:22:41.465710
——————————————————————————–

Name : glibc
Product : Fedora 27
Version : 2.26
Release : 20.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 fixes minor security bugs (CVE-2017-17426, CVE-2017-15804), contains
single-threaded optimizations for `malloc`, and increases compatibility with IBM
POWER 9 hardware.
