CyberRota Analysis
AI-GeneratedThe vulnerability affects the HDF5 library in F5 products, where improper validation of the `cd_values` array can lead to a denial of service when processing specially crafted HDF5 files. Attackers can exploit this flaw by triggering crashes through files that contain an N-Bit filter with insufficient client-data values. Organizations using affected F5 products should prioritize patching to mitigate potential service disruptions.

Original NVD Description
H5Z__filter_nbit in H5Znbit.c in HDF5 through 2.3.0 dereferences cd_values[0] through cd_values[4] without validating that cd_values is non-NULL or that cd_nelmts is at least 5, the fixed size of the filter's header. This allows attackers to cause a denial of service via a crafted HDF5 file that stores the N-Bit filter pipeline message with zero client-data values, opened and read via H5Dread, e.g. by the h5ls or h5repack tools.
