RHEL 7 : glib2 and ibus (RHSA-2020:3978)

critical Nessus Plugin ID 141023

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for glib2 / ibus.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:3978 advisory.

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:

For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.9 Release Notes linked from the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL glib2 / ibus packages based on the guidance in RHSA-2020:3978.
