How to fix?

Upgrade Ubuntu:16.04 libdbi-perl to version 1.634-1ubuntu0.2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libdbi-perl package and not the libdbi-perl package as distributed by Ubuntu. See How to fix? for Ubuntu:16.04 relevant fixed versions and status.

An issue was discovered in the DBI module before 1.643 for Perl. The hv_fetch() documentation requires checking for NULL and the code does that. But, shortly thereafter, it calls SvOK(profile), causing a NULL pointer dereference.
