CVE-2020-25666  (opens in a new tab)

How to fix?

Upgrade ImageMagick/ImageMagick to version 6.9.10-69, 7.0.9-0 or higher.

Overview

Affected versions of this package are vulnerable to Integer Overflow or Wraparound. There are 4 places in HistogramCompare() in MagickCore/histogram.c where an integer overflow is possible during simple math calculations. This occurs in the rgb values and count value for a color. The patch uses casts to ssize_t type for these calculations, instead of int. This flaw could impact application reliability in the event that ImageMagick processes a crafted input file. This flaw affects ImageMagick versions prior to 7.0.9-0.
