| Title | https://github.com/HDFGroup/hdf5 HDF5 1.14.6 Heap-based Buffer Overflow |
|---|
| Description | A heap-buffer-overflow vulnerability was discovered in the H5F_addr_encode_len function within the HDF5 Library. This issue occurs when processing certain files, leading to an out-of-bounds write and potential application crash.
The vulnerability arises in the H5F_addr_encode_len function defined in src/H5Fint.c at line 2959.
The reason for this phenomenon is that the H5F_addr_encode_len function did not perform a buffer boundary check when assigning values to the address pointed to by pp, mistakenly writing bytes to areas outside the boundary, resulting in a buffer overflow of at least 1 byte. |
