CVE-2025-2924 Details
Description
A vulnerability, which was classified as problematic, was found in HDF5 up to 1.14.6. This affects the function H5HL__fl_deserialize of the file src/H5HLcache.c. The manipulation of the argument free_block 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.
A heap-based buffer overflow vulnerability has been identified in the HDF5 library, affecting versions prior to 1.14.6. The issue arises in the H5HL__fl_deserialize function within src/H5HLcache.c, where the free_block argument is not properly validated. This oversight allows for an overflow when processing certain files, leading to an out-of-bounds read and potential application crash. The vulnerability can be exploited locally.
Users are advised to update to HDF5 version 1.14.6 or later, where this vulnerability has been addressed.
