CVE-2026-28688

Impact

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 Shadow bytes around the buggy address: 0x0a4e80007450: fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd 0x0a4e80007460: fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd 0x0a4e80007470: fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd 0x0a4e80007480: fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd 0x0a4e80007490: fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd =>0x0a4e800074a0: fd fd fd fd fd fd fd fd fd fd[fd]fd fd fd fd fd 0x0a4e800074b0: fd fd fd fd fd fd fd fd fd fa fa fa fa fa fa fa 0x0a4e800074c0: fa fa fa fa fa fa fa fa fa fa fa fa fa fa fa fa 0x0a4e800074d0: fa fa fa fa fa fa fa fa fa fa fa fa fa fa fa fa 0x0a4e800074e0: fa fa fa fa fa fa fa fa fa fa fa fa fa fa fa fa 0x0a4e800074f0: fa fa fa fa fa fa fa fa fa fa fa fa fa fa fa fa ```
