Echo: hdf5: security update to 1.14.5+repack-3+e17

medium Tenable Cloud Security Plugin ID 478307

Description

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

 - HDF5 through 2.2.0 contains an uncontrolled recursion vulnerability in H5B__iterate_helper() in src/H5B.c.
 When iterating a version 1 B-tree, the function does not verify that a child node’s level matches the
 expected level. That check is performed only in H5B__cache_deserialize() when a node is first loaded into
 the metadata cache. A crafted HDF5 file whose B-tree child pointer refers back to a node already in the
 cache, such as a node that points to itself, bypasses the check and causes unbounded recursion, leading to
 stack exhaustion and a crash. This can be triggered by calling H5Gget_info() or H5Gget_num_objs() on a
 group in the crafted file, which reaches H5B_iterate() through H5G__obj_info() and H5G__stab_count(). An
 attacker who can get a user or application to open a malicious file can cause a denial of service.
 (CVE-2026-120689)

Solution

Update the hdf5 library and its related packages to version 1.14.5+repack-3+e17 or later.
