| Title | https://github.com/HDFGroup/hdf5 HDF5 v1.14.6 Heap-based Buffer Overflow |
|---|
| Description | A heap-buffer-overflow vulnerability was discovered in the H5F__accum_free 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 H5F__accum_free function defined in src/H5Faccum.c at line 885. The function failed to correctly check the value of overlap_size (which may be a large value) and buffer boundaries, resulting in buffer overflow and read operations exceeding allocated memory when calling function memmove. |
