Summary

ImageMagick from 7.1.0-21 before 7.1.2-32 contains a heap buffer over-read in its handling of the -fx option (CWE-125). A certain -fx operation reads beyond an allocated heap buffer in specific situations. A local attacker with low privileges who can get a crafted -fx expression processed can read limited out-of-bounds heap memory.
