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

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

  - The DataRow.Decode function fails to properly validate field lengths. A malicious or compromised     PostgreSQL server can send a DataRow message with a negative field length, causing a slice bounds out of     range panic. (CVE-2026-32286)

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