"It was found that the function ST_AsX3D in PostGIS, a module that adds
spatial objects to the PostgreSQL object-relational database, did not
handle empty values properly, allowing malicious users to cause denial
of service or possibly other unspecified behaviour.

For Debian 8 'Jessie', this problem has been fixed in version
2.1.4+dfsg-3+deb8u1.

We recommend that you upgrade your postgis packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
