CVE-2026-105614— PostgreSQL Anonymizer: Unbounded image-decode memory allocation (DoS) in anon.image_blur()

Quick assessment

Affected

DALIBO PostgreSQL Anonymizer

Exploitation

No confirmed in-the-wild exploitation; assess based on exposure

Recommended action

Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

PostgreSQL Anonymizer 的函数未对提供的图像所声明的尺寸进行校验，攻击者可借此提交一张实际尺寸很小但声明尺寸极大的图像。该漏洞可被利用以耗尽后端服务器的内存，并在开启内存超分（overcommit）时触发 OOM（内存不足）终止，进而导致整个集群发生崩溃并进入恢复流程。该问题已在 PostgreSQL Anonymizer 3.3.0 及更高版本中得到修复。

Vulnerability Title

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

Source: CVE Program / CVE List V5

Vulnerability 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.
