Technical details
A heap buffer over-read exists in the fx.c module of ImageMagick when processing the -fx option. The vulnerability occurs in the GetIntensity function where an array index is incorrectly dereferenced, causing out-of-bounds memory access. An attacker who can provide a crafted -fx expression to a local user can read limited heap memory contents; the fix involves correcting the array indexing in MagickCore/fx.c.
