CVE-2019-12761 (opens in a new tab)How to fix?
Upgrade Ubuntu:18.04 pyxdg to version 0.25-4ubuntu1.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream pyxdg package and not the pyxdg package as distributed by Ubuntu.
See How to fix? for Ubuntu:18.04 relevant fixed versions and status.
A code injection issue was discovered in PyXDG before 0.26 via crafted Python code in a Category element of a Menu XML document in a .menu file. XDG_CONFIG_DIRS must be set up to trigger xdg.Menu.parse parsing within the directory containing this file. This is due to a lack of sanitization in xdg/Menu.py before an eval call.
