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

  - DCMTK through 3.6.6 does not handle memory free properly. The object in the program is free but its     address is still used in other locations. Sending specific requests to the dcmqrdb program will incur a     double free. An attacker can use it to launch a DoS attack. (CVE-2021-41688)

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

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3847 advisory.
