Fedora 32: FEDORA-2020-444c372453 Medium: Glibc Security Issues

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 incorporates fixes from the upstream glibc 2.31 stable release

branch, including 2 fixes for medium severity security vulnerabilities.

(CVE-2020-10029, CVE-2020-1752)
