Fedora 35: 2022-2f3c8efcb5 High: Libxml2 Buffer Overflow Patch

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 glibc update fixes a use-after-free in the `mq_notify` function

(CVE-2021-33574).
