23th percentile - higher than 23% of all known CVEs

Summary

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.

Risk Assessment

An authenticated database user can leak sensitive data from memory or cause a crash of the PostgreSQL service, leading to a denial of service.

Recommendation

Update pgPointcloud to a version later than 1.2.5 if available, or restrict database user privileges to a minimum.
