 Bug Fixes since HDF5-1.8.20
 ===========================
 
-    - 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 filter pipeline message which contains
-      a 'number of filters' field that exceeds the actual number of
-      filters in the message, the HDF5 C library will read off the end of
-      the read buffer.
-
-      This issue was reported to The HDF Group as issue #CVE-2017-17506.
-
-      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.
-
-      The problem was fixed by passing the buffer size with the buffer
-      and ensuring that the pointer cannot be incremented off the end
-      of the buffer. A mismatch between the number of filters declared
-      and the actual number of filters will now invoke normal HDF5
-      error handling.

-
-    - If an HDF5 file contains a malformed compound datatype with a
-      suitably large offset, the type conversion code can run off
-      the end of the type conversion buffer, causing a segmentation
-      fault.
-
-      This issue was reported to The HDF Group as issue #CVE-2017-17507.
-
-      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.
-
-      THE HDF GROUP WILL NOT FIX THIS BUG AT THIS TIME
-
-      Fixing this problem would involve updating the publicly visible
-      H5T_conv_t function pointer typedef and versioning the API calls
-      which use it. We normally only modify the public API during
-      major releases, so this bug will not be fixed at this time.
-
-      (DER - 2018/02/26, HDFFV-10356)
-
-    - 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.
-
-      This issue was reported to The HDF Group as issue #CVE-2017-17508.
-
-      NOTE: The HDF5 C library cannot produce such a file. This condition
-            should only occur in a corrupt (or deliberately altered) file

-
-      Checking for zero before dividing fixes the problem. Instead of the
-      division by zero, the normal HDF5 error handling is invoked.

-
-    - If an HDF5 file contains a malformed symbol table node that declares
-      it contains more symbols than it actually contains, the library
-      can run off the end of the metadata cache buffer while processing
-      the symbol table node.

-      This issue was reported to The HDF Group as issue #CVE-2017-17509.

-
-      Update CMake commands configuration.
-
-      A number of improvements were made to the CMake commands. Most
-      changes simplify usage or eliminate unused constructs. Also,
-      some changes support better cross-platform support.

-      Correct usage of CMAKE_BUILD_TYPE variable.
-
-      The use of the CMAKE_BUILD_TYPE is incorrect for multi-config
-      generators (Visual Studio and XCode) and is optional for single
-      config generators. Created a new macro to check
-        GLOBAL PROPERTY -> GENERATOR_IS_MULTI_CONFIG
-      Created two new HDF variable, HDF_BUILD_TYPE and HDF_CFG_BUILD_TYPE.
-      Defaults for these variables is "Release".
-
-      (ADB - 2018/01/10, HDFFV-10385)

-
-      HDFFV-10297, HDFFV-10319 reworked code for h5repack and h5diff code
-      in the tools library. The check for an existing layout was incorrectly

-      the tools library will hide the error stack during file open.
-
-      While this is preferable almost always, there are reasons to enable
-      display of the error stack when a tool will not open a file. Adding an
-      optional argument to the --enable-error-stack will provide this use case.
-      As an optional argument it will not affect the operation of the
-      --enable-error-stack. h5dump is the only tool to implement this change.

-      h5dump would output an indented blank line in the filters section.
-
-      h5dump overused the h5tools_simple_prefix function, which is a
-      function intended to account for the data index (x,y,z) option.

-    - h5repack
-
-      h5repack incorrectly searched internal object table for name.
-
-      h5repack would search the table of objects for a name, if the
-      name did not match it tried to determine if the name without a
-      leading slash would match. The logic was flawed! The table
-      stored names(paths) without a leading slash and did a strstr
-      of the table path to the name.
-      The assumption was that if there was a difference of one then
-      it was a match, however "pressure" would match "/pressure" as
-      well as "/pressure1", "/pressure2", etc. Changed logic to remove
-      any leading slash and then do a full compare of the name.

-
-      Reworked solution for HDFFV-8625 and HDFFV-8639. Implemented the check
-      for string objects of same type in the diff_can_type function by
-      adding an if(tclass1 == H5T_STRING) block. This if block moves the
-      same check that was added for attributes to this function, which is
-      used by all object types. This function also handles complex type
-      structures.
-      Also added a new test file in h5diffgenttest for testing this issue
-      and removed the temporary files used in the test scripts.
