NVD Description

Note: Versions mentioned in the description apply only to the upstream postgresql:12/postgresql-plpython3 package and not the postgresql:12/postgresql-plpython3 package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

Type confusion regarding input of PostgreSQL ctid data type selectivity estimator allows an object creator to view a calculation derived from the value of an arbitrary 4-byte span of memory, via a chosen non-ctid input. While the calculation loses precision, substantial memory value recovery appears possible. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.
