A vulnerability, which was classified as problematic, was found in HDF5 1.14.6. Affected is the function H5FS__sect_link_size of the file src/H5FSsection.c. The manipulation leads to heap-based buffer overflow. It is possible to launch the attack on the local host. The exploit has been disclosed to the public and may be used.
AnalysisAI
Heap-based buffer overflow in HDF5 1.14.6 allows local attackers with low privileges to cause application crashes or potential arbitrary code execution. The flaw resides in the H5FS__sect_link_size function, and a publicly available exploit exists. EPSS predicts a very low exploitation probability (0.04%), and no active exploitation has been observed.
