Fedora 27: glibc Security Update

December 19, 2017

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.

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 fixes minor security bugs (CVE-2017-17426, CVE-2017-15804), contains

single-threaded optimizations for `malloc`, and increases compatibility with IBM

POWER 9 hardware.
