Description Andrej Nemec 2017-04-11 12:39:43 UTC

A vulnerability was found in ImageMagick. An infinite loop can occur because of a floating-point rounding error in some of the color algorithms. This affects ModulateHSL, ModulateHCL, ModulateHCLp, ModulateHSB, ModulateHSI, ModulateHSV, ModulateHWB, ModulateLCHab, and ModulateLCHuv. 

A maliciously crafted file could cause the application to become unresponsive.
