Use After Free
magick/attribute.c in ImageMagick 7.0.3-2 allows remote attackers to cause a denial of service (use-after-free) via a crafted file.
CWE-416 - Use After Free
Use-after-free (UaF) vulnerability occurs when the application is using a pointer to memory that has been freed. Any attempt to read/write to a buffer after it is de-allocated allows memory corruption, sensitive information exposure, and can potentially lead to arbitrary code execution.
