Description Pedro Sampaio 2017-07-03 14:59:29 UTC
An issue was discovered in GraphicsMagick 1.3.25. When a MATLAB image is processed in coders/mat.c, it can lead to a out of memory denial of service in ReadMATImage() if the size specified in metadata for a MAT Object is larger than the actual amount of data.
