CVE-2026-116151— ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 Memory Leak in JNG Encoder

Quick assessment

Affected

ImageMagick ImageMagick

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.

ImageMagick 6.9.13-58 之前的版本以及 7.x 系列中 7.1.2-33 之前的版本，其 JNG 编码器存在内存泄漏漏洞。在处理特制的图像时，该编码器未能释放已分配的内存。攻击者可提供经特制处理并编码为 JNG 格式的图像，从而引发内存泄漏，可能导致资源耗尽，进而造成有限拒绝服务（DoS）。
