Titlehttps://github.com/HDFGroup/hdf5 HDF5 1.14.6 Heap-based Buffer Overflow
DescriptionA heap-buffer-overflow vulnerability was discovered in the H5HL__fl_deserialize function within the HDF5 Library. This issue occurs when processing certain files, leading to an out-of-bounds read and potential application crash. The vulnerability arises in the H5HL__fl_deserialize function defined in src/H5HLcache.c at line 247. The reason is that function H5HL__fl_deserialize did not check whether the value of free_block is valid or within the specified boundary when calling H5_DECODE_LENGTH_LEN. When the value of free_block is a large number, it can lead to overflow and potential segmentation fault.
