Fedora Update Notification
FEDORA-2020-244efc27af

Name        : glibc
Product     : Fedora 31
Version     : 2.30
Release     : 11.fc31
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 incorporates fixes from the upstream glibc 2.30 stable release
branch, including 3 fixes for medium severity security vulnerabilities.
(CVE-2020-10029, CVE-2020-1752, CVE-2020-1751)
