A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 20.04 LTS - Ubuntu 19.10 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS


APT could be made to crash if it opened a specially crafted file.

Software Description: - apt: Advanced front-end for dpkg


It was discovered that APT incorrectly handled certain filenames during package installation. If an attacker could provide a specially crafted package to be installed by the system administrator, this could cause APT to crash.
