Echo: hdf5: security update to 1.14.5+repack-3+e12

medium Tenable Cloud Security Plugin ID 464978

Description

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

 - HDF5 is a high-performance library and a file format specification that implements the HDF5 data model. If
 a file is corrupted such that an array datatype's size, the number of elements, and the element size are
 not in agreement it can trigger an out of bounds read. The array datatype stores the full size of the
 datatype (`dt->shared->size`) separately from the number of elements (`dt->shared->u.array.nelem`) and the
 element size (`dt->shared->parent->shared->size`). If any one of these are corrupted so that they don't
 align with the others (element size * nelem = full size), it can lead to an out of bounds read. Depending
 on what is corrupted, it can alter the type of out of bounds read triggered. The vulnerability is present
 only in files that have been maliciously altered, as its generally not possible to independently alter the
 full size of the datatype, the element count and the element size. As such, this is only present if a
 malicious actor is altering files, and won't appear in regular usage. (CVE-2026-26197)

Solution

Update the hdf5 library and its related packages to version 1.14.5+repack-3+e12 or later.
