Description

The remote Ubuntu 20.04 LTS / 22.04 LTS / 23.10 host has packages installed that are affected by a vulnerability as referenced in the USN-6589-1 advisory.

 Fabian Baeumer, Marcus Brinkmann and Joerg Schwenk discovered that the SSH protocol used in FileZilla is prone to a prefix truncation attack, known as the Terrapin attack. A remote attacker could use this issue to downgrade or disable some security features and obtain sensitive information.
