Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-5901-1 advisory.

 Hubert Kario discovered that GnuTLS had a timing side-channel when handling certain RSA messages. A remote attacker could possibly use this issue to recover sensitive information.

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.
