pgPointcloud through 1.2.5 contains a heap out-of-bounds read vulnerability in dimensional patch WKB deserialization that allows authenticated database users to read adjacent heap memory. Attackers can supply crafted pcpatch values with attacker-controlled size fields to copy heap memory into stored patches for exfiltration or crash the PostgreSQL backend.
