(DER - 2017/11/21, HDFFV-10330)
+ - If an HDF5 file contains a filter pipeline message with a 'number of
+ filters' field that exceeds the maximum number of allowed filters,
+ the error handling code will attempt to dereference a NULL pointer.
+
+ This issue was reported to The HDF Group as issue #CVE-2017-17505.
+
+ NOTE: The HDF5 C library cannot produce such a file. 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.
+

- If an HDF5 file contains a malformed compound type which contains
a member of size zero, a division by zero error will occur while
processing the type.
