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

critical Nessus Plugin ID 141023

Synopsis

The remote Red Hat host is missing one or more security updates.

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.

- 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)

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

Solution
