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是ImageMagick团队开源的一套开源的图像处理软件。可读取、转换或写入多种格式的图片。 ImageMagick 7.1.2-22之前版本和6.9.13-47之前版本存在数字错误漏洞，该漏洞源于二项式内核处理中的除零漏洞，攻击者可以通过提供较大的二项式内核值导致整数溢出，进而引发除零错误和应用程序崩溃，导致拒绝服务。
