The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3084 advisory.
In nDPI through 3.2, the H.323 dissector is vulnerable to a heap-based buffer over-read in ndpi_search_h323 in lib/protocols/h323.c, as demonstrated by a payload packet length that is too short.
(CVE-2020-15472)
In nDPI through 3.2, the Oracle protocol dissector has a heap-based buffer over-read in ndpi_search_oracle in lib/protocols/oracle.c. (CVE-2020-15476)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
