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 在 7.1.2-31 及 6.9.13-56 之前的版本中，其 FLIF 编码器存在一个除以零的缺陷。当被编码图像中的“每秒帧数”（ticks per second）取值不正确时，会导致编码器发生除零错误并崩溃，从而导致服务中断。该问题已在 7.1.2-31 和 6.9.13-56 版本中修复。
