Summary
ImageMagick has heap use-after-free in the MSL encoder
Details
A heap-use-after-free vulnerability exists in the MSL encoder, where a cloned image is destroyed twice. The MSL coder does not support writing MSL so the write capability has been removed.
SUMMARY: AddressSanitizer: heap-use-after-free MagickCore/image.c:1195 in DestroyImage
