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，在其 DJVU 解码器中存在空指针解引用漏洞。该漏洞的成因是：在使用内存分配结果之前，未对其分配是否成功进行检查。攻击者可构造特制的 DJVU 图像，在触发内存分配失败的场景下，导致处理进程崩溃，从而引发拒绝服务（DoS）。

Vulnerability Title
ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 Null Pointer Dereference in DJVU Decoder
Source: CVE Program / CVE List V5
Vulnerability Description
ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 contains a null pointer dereference in the DJVU decoder because the result of a memory allocation is not checked before use. Attackers can supply a DJVU image that, when processed under conditions where the allocation fails, crashes the process and causes a denial of service.
