3. Description:

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)

For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.

Additional Changes:
