Overview
Affected versions of this package are vulnerable to Out-of-bounds Write in the ST_AsText function when processing deeply nested GeometryCollections due to insufficient buffer allocation during recursive WKT serialization. An attacker can corrupt server memory or terminate the database daemon by submitting specially crafted GIS objects. This is only exploitable if the attacker is an authenticated user with basic query privileges.
