    Published: 28 Oct 2026Last Modified: 7 Nov 2026

    Summary: PostgreSQL Anonymizer: Unbounded memory allocation (DoS) in range-based dummy functions

    Details: PostgreSQL Anonymizer's range-based dummy functions dont constraint the range size. This vulnerability can be exploited to exhaust the memory of a backend and OOM-kill it (when ovecommit is on), which results in a cluster-wide crash recovery. The problem is resolved in PostgreSQL Anonymizer 3.3.0 and later versions.
