(RHSA-2020:3978) Moderate: glib2 and ibus security and bug fix update

GLib provides the core application building blocks for libraries and applications written in C. It provides the core object system used in GNOME, the main loop implementation, and a large set of utility functions for strings and common data structures.

The Intelligent Input Bus (IBus) is an input method framework for multilingual input in Unix-like operating systems.

Security Fix(es):

• glib2: file_copy_fallback in gio/gfile.c in GNOME GLib does not properly restrict file permissions while a copy operation is in progress (CVE-2019-12450)

• ibus: missing authorization allows local attacker to access the input bus of another user (CVE-2019-14822)
