CVE-2020-25666
Low 3.3
In plain English
A low-severity integer overflow in ImageMagick. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 1.2% (higher than 68% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official 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.
