- Exploited in the wild: not listed in CISA KEV
- EPSS: 1.2% probability of exploitation in the next 30 days

Description
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.
Affected products
- Debian Linux: 9.0
- ImageMagick: before 6.9.10-69; from 7.0.0-0 before 7.0.9-0 — fixed in 6.9.10-69, 7.0.9-0
How to fix
Upgrade to a fixed version: ImageMagick 6.9.10-69, 7.0.9-0. Check the vendor advisory for mitigations.
