"Two issues have been found in nfdump, a netflow capture daemon. Both
issues are related to either a buffer overflow or an integer overflow,
which could result in a denial of service or a local code execution.

For Debian 9 stretch, these problems have been fixed in version
1.6.15-3+deb9u1.

We recommend that you upgrade your nfdump packages.

For the detailed security status of nfdump please refer to its
security tracker page at:

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