The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - borgbackup is an opensource, deduplicating archiver with compression and authenticated encryption. A flaw     in the cryptographic authentication scheme in borgbackup allowed an attacker to fake archives and     potentially indirectly cause backup data loss in the repository. The attack requires an attacker to be     able to: 1. insert files (with no additional headers) into backups and 2. gain write access to the     repository. This vulnerability does not disclose plaintext to the attacker, nor does it affect the     authenticity of existing archives. Creating plausible fake archives may be feasible for empty or small     archives, but is unlikely for large archives. The issue has been fixed in borgbackup 1.2.5. Users are     advised to upgrade. Additionally to installing the fixed code, users must follow the upgrade procedure as     documented in the change log. Data loss after being attacked can be avoided by reviewing the archives     (timestamp and contents valid and as expected) after any borg check --repair and before borg prune.
    There are no known workarounds for this vulnerability. (CVE-2023-36811)

Note that Nessus relies on the presence of the package as reported by the vendor.
