Fedora Update Notification
2020-07-19 01:08:45.469519

Name : glibc
Product : Fedora 32
Version : 2.31
Release : 4.fc32
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 incorporates fixes from the upstream glibc 2.31 stable release
branch, including a fix for a medium severity security vulnerability.
