CVE-2017-6313

Integer underflow in the load_resources function in io-icns.c in gdk-pixbuf allows context-dependent attackers to cause a denial of service (out-of-bounds read and program crash) via a crafted image entry size in an ICO file.

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.
