How to fix?

There is no fixed version for vtk.

Overview

Affected versions of this package are vulnerable to Out-of-bounds Write in the vtkDEMReader::ReadProfiles method in IO/Image/vtkDEMReader.cxx, which derives rowId and lastRow from the file-supplied profileId[0] and profileSize[0] of a USGS DEM B-record and never checks them against the grid's numberOfRows and numberOfColumns. An attacker can write past the end of the allocated vtkImageData buffer, and crash the process, by supplying a DEM file whose profile prefix drives the *(outPtr + columnId + row * numberOfColumns) store loop beyond the image bounds. Exploitation requires the application to parse the attacker-supplied .dem file with vtkDEMReader.
