CVE-2017-18359: Debian Linux

High severity, CVSS 7.5. EPSS: 3% chance of exploitation in the next 30 days.

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.

Affected products

• Debian Debian Linux: version 8.0 only; version 9.0 only
• Postgis Postgis: from 2.0.0, before 2.3.3 (fixed in 2.3.3)
