"The remote Debian host is missing a security update.");

"It was found that SNMP Trap Translator does not drop privileges as
configured and does not properly escape shell commands in certain
functions. A remote attacker, by sending a malicious crafted SNMP
trap, could possibly execute arbitrary shell code with the privileges
of the process or cause a Denial of Service condition.

For Debian 9 stretch, this problem has been fixed in version
1.4-1+deb9u1.

We recommend that you upgrade your snmptt packages.

For the detailed security status of snmptt 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.");
