Subject: Compound datatypes may not have members of size 0
Patch-mainline: Not yet
Git-repo: ssh://eich@192.168.122.1:/home/eich/sources/HPC/hdf5
Git-commit: 88ea94d38fdfecba173dbea18502a5f82a46601b
References:
A member size of 0 may lead to an FPE later on as reported in
CVE-2021-46244. To avoid this, check for this as soon as the
member is decoded.
This should probably be done in H5O_dtype_decode_helper() already,
however it is not clear whether all sizes are expected to be != 0.
This fixes CVE-2021-46244.

Malformed hdf5 files may provide more dimensions than the array dim[] is
able to hold. Check number of elements first by calling
H5Sget_simple_extent_dims() with NULL for both 'dims' and 'maxdims' arguments.

Patch-mainline: Not yet
Git-repo: ssh://eich@192.168.122.1:/home/eich/sources/HPC/hdf5
Git-commit: d39a27113ef75058f236b0606a74b4af5767c4e7
References:
The size of the enumeration values is determined by the size of the parent.
Functions accessing the enumeration values use the size of the enumartion
to determine the size of each element and how much data to copy. Thus the
size of the enumeration and its parent need to match.
Check here to avoid unpleasant surprises later.
This fixes CVE-2018-14031.

Subject: Hot fix for CVE-2020-10812
Patch-mainline: Not yet
Git-repo: ssh://eich@192.168.122.1:/home/eich/sources/HPC/hdf5
Git-commit: 2465fc41d208d57eb0d7d025286a81664148fbaf
References:
CVE-2020-10812 unveils a more fundamental design flaw in H5F__dest():
this function returns FAIL if one of multiple operations fail (in this
case H5AC_prep_for_file_close()) while it still proceeds to prepare the
close operation, free the 'shared' member in struct H5F_t and ulimately
deallocate the structure itself.
When H5F__dest() signals back FAIL to the caller, the caller itself
(H5F_try_close() in this case) will fail. This failure is signalled
up the stack, thus the file will not be considered closed and another
attempt will be made to close it - latest in the exit handler.
The next attempt to close will however need the already deallocated
H5F_t structure and the H5T_shared_t structure in its 'shared' member,
however.
This fix papers over the failure of H5AC_prep_for_file_close() by not
changing the return status of H5F__dest() to fail. There are numerous
other opportunities where this will happen.
This may call for a more fundamental solution.

Subject: Report error if dimensions of chunked storage in data layout < 2
Patch-mainline: Not yet
Git-repo: ssh://eich@192.168.122.1:/home/eich/sources/HPC/hdf5
Git-commit: 34b621424504265cff3c33cf634a70efb52db180
References:
For Data Layout Messages version 1 & 2 the specification state
that the value stored in the data field is 1 greater than the
number of dimensions in the dataspace. For version 3 this is
not explicitly stated but the implementation suggests it to be
the case.
Thus the set value needs to be at least 2. For dimensionality
< 2 an out-of-bounds access occurs as in CVE-2021-45833.
This fixes CVE-2021-45833.

Subject: Validate location (offset) of the accumulated metadata when comparing
Patch-mainline: Not yet
Git-repo: ssh://eich@192.168.122.1:/home/eich/sources/HPC/hdf5
Git-commit: 2cf9918ae66f023a2b6d44eb591ee2ac479a6e53
References:
Initially, the accumulated metadata location is initialized to HADDR_UNDEF
- the highest available address. Bogus input files may provide a location
or size matching this value. Comparing this address against such bogus
values may provide false positives. This make sure, the value has been
initilized or fail the comparison early and let other parts of the
code deal with the bogus address/size.
Note: To avoid unnecessary checks, we have assumed that if the 'dirty'
member in the same structure is true the location is valid.
This fixes CVE-2018-13867.
