|---|
| Description | A heap-use-after-free vulnerability was discovered in the H5FL__blk_gc_list 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 H5FL__blk_gc_list function defined in src/H5FL.c at line 985. This function does not check whether the lists in multiple chunks point to the same block address, resulting in duplicated addresses that have already been freed. |
