"An issue has been found in ndpi, an extensible deep packet inspection
library. The Oracle protocol dissector contains an heap-based buffer
over-read, which could crash the application that uses this library
and may result in denial of service.

For Debian 9 stretch, this problem has been fixed in version
1.8-1+deb9u1.

We recommend that you upgrade your ndpi packages.

For the detailed security status of ndpi please refer to its security
tracker page at: https://security-tracker.debian.org/tracker/ndpi

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
