CVE-2017-18359 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. PostGIS 2.x before 2.3.3, as used with PostgreSQL, allows remote attackers to cause a denial of service via crafted ST_AsX3D function input, as demonstrated by an abnormal server termination for "SELECT ST_AsX3D('LINESTRING EMPTY');" because empty geometries are mishandled.. EPSS estimates a 3.05% chance of exploitation in the next 30 days.
