Echo: hdf5: security update to 1.14.5+repack-3+e13

medium Tenable Cloud Security Plugin ID 460823

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- The H5Z__nbit_decompress_one_byte, H5Z__nbit_decompress_one_nooptype, and H5Z__nbit_decompress_one_atomic
functions in H5Znbit.c in HDF5 prior to 2.3.0 advance a read index into the compressed chunk buffer
without bounding it against the buffer's actual size. This allows attackers to cause an out-of-bounds heap
read, and in constrained cases disclosure of adjacent heap memory into decompressed dataset values, via a
crafted HDF5 file whose N-Bit filter parameters describe more decompressed data than the stored compressed
chunk actually contains, triggered via H5Dread, e.g. by the h5ls or h5repack tools. (CVE-2026-19027)

Solution

Update the hdf5 library and its related packages to version 1.14.5+repack-3+e13 or later.
