This condition + should only occur in a corrupt (or deliberately altered) file + or a file created by third-party software. + + This problem arose because the error handling code assumed that + the 'number of filters' field implied that a dynamic array of that + size had already been created and that the cleanup code should + iterate over that array and clean up each element's resources. If + an error occurred before the array has been allocated, this will + not be true. + + This has been changed so that the number of filters is set to + zero on errors. Additionally, the filter array traversal in the + error handling code now requires that the filter array not be NULL. + + (DER - 2018/02/06, HDFFV-10354) + Configuration ------------- - CMake |
