Name of the Vulnerable Software and Affected Versions PostgreSQL versions prior to 18.5 PostgreSQL versions prior to 17.11 PostgreSQL versions prior to 16.15 PostgreSQL versions prior to 15.19 PostgreSQL versions prior to 14.24

Description Type confusion in the 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 by using a chosen non-ctid input. Although the resulting calculation loses precision, it is possible to recover substantial memory values, potentially leading to the disclosure of protected information.

Recommendations Update to version 18.5 or later. Update to version 17.11 or later. Update to version 16.15 or later. Update to version 15.19 or later. Update to version 14.24 or later.
