========================================================================== Ubuntu Security Notice USN-4700-1 January 19, 2021
pyxdg vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 18.04 LTS - Ubuntu 16.04 LTS - Ubuntu 14.04 ESM
Summary:
PyXDG could be made to run programs as your login if it received specially crafted input.
Software Description: - pyxdg: python library to access freedesktop.org standards
Details:
Alexandre D'Hondt discovered that PyXDG did not properly sanitize input. An attacker could exploit this with a crafted .menu file to execute arbitrary code.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 18.04 LTS: python-xdg 0.25-4ubuntu1.1 python3-xdg 0.25-4ubuntu1.1
Ubuntu 16.04 LTS: python-xdg 0.25-4ubuntu0.16.04.1 python3-xdg 0.25-4ubuntu0.16.04.1
Ubuntu 14.04 ESM: python-xdg 0.25-4ubuntu0.14.04.1~esm1 python3-xdg 0.25-4ubuntu0.14.04.1~esm1
In general, a standard system update will make all the necessary changes.
