A NULL pointer dereference vulnerability in the H5Pget_fill_value function of HDF5 versions prior to 2.1.1 can be exploited by attackers to trigger a denial of service. This issue arises when a dataset's fill value message has a negative size field, leading to potential application crashes. Organizations using affected F5 products should prioritize patching this vulnerability to mitigate the risk of service disruptions.

Original NVD Description

NULL pointer dereference in H5Pget_fill_value in HDF5 before 2.3.0 allows attackers to cause a denial of service via a dataset whose version 1 or 2 fill value message has the "defined" flag set together with a negative size field, which is not normalized to the library's "undefined" sentinel and reaches H5T_path_find with a NULL datatype.
