Recommended action

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

ImageMagick 7.1.2-33 之前的版本在 UHDR 解码器中存在策略绕过漏洞。由于扩展检查（extent checks）在解码完成后才执行，攻击者可利用该漏洞规避图像宽度和高度限制。攻击者可以提交精心构造的、具有超大尺寸的 UHDR 图像，这些图像会在策略限制生效前被完全解码，从而导致系统资源过度消耗。

Vulnerability Title

ImageMagick before 7.1.2-33 Policy Bypass in UHDR Decoder

Source: CVE Program / CVE List V5

Vulnerability Description

ImageMagick before 7.1.2-33 contains a policy bypass vulnerability in the UHDR decoder that allows attackers to evade image width and height limits because extent checks occur after decoding. Attackers can supply crafted UHDR images with oversized dimensions that are fully decoded before policy limits are enforced, causing excessive resource consumption.
