The remote Ubuntu 20.04 LTS / 22.04 LTS / 23.10 host has a package installed that is affected by a vulnerability as referenced in the USN-6598-1 advisory.

    Fabian Bumer, Marcus Brinkmann, Jrg Schwenk discovered that the SSH protocol was vulnerable to a     prefix truncation attack. If a remote attacker was able to intercept SSH communications, extension     negotiation messages could be truncated, possibly leading to certain algorithms and features being     downgraded. This issue is known as the Terrapin attack. This update adds protocol extensions to mitigate     this issue.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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