CWEhttps://cwe.mitre.org/data/definitions/191.html

Integer underflow in the pixman_trapezoid_valid macro in pixman.h in Pixman before 0.32.0, as used in X.Org server and cairo, allows context-dependent attackers to cause a denial of service (crash) via a negative bottom value.

Weakness

The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result.
