PostgreSQL Anonymizer: Unbounded image-decode memory allocation (DoS) in anon.image_blur()

Impact

PostgreSQL Anonymizer's `anon.image_blur()` function has an unbounded memory allocation weakness, allowing an attacker to exhaust backend memory. Affected versions are less than 3.3.0. This can cause a cluster-wide crash recovery.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

What to do

Revoke execution rights on the range-based dummy functions or drop them.

Original source description

PostgreSQL Anonymizer's anon.image_blur() function doesn't check the declared dimension of the provided image, allowing an attacker to provide a small image with enormous declared dimensions. 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.
