Echo: hdf5: security update to 1.14.5+repack-3+e19

medium Tenable Cloud Security Plugin ID 478405

Description

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

 - HDF5 through 2.2.0 contains a NULL pointer dereference vulnerability in H5HL_unprotect() in src/H5HL.c.
 H5HL_protect() pins a single metadata cache entry for a local heap, either the heap prefix or the separate
 data block, and H5HL_unprotect() unpins it on the final unprotect. When the metadata cache destroys a
 corrupted local heap entry, H5HL__prfx_dest() unlinks it from the heap by setting heap->prfx or heap->dblk
 to NULL. A crafted HDF5 file can therefore reach H5HL_unprotect() with no cached object to unpin, and the
 function passes the NULL pointer to H5AC_unpin_entry(). This causes an assertion failure in debug builds
 and a NULL pointer dereference and crash in release builds. An attacker who can get a user or application
 to open and traverse a malicious file can cause a denial of service. (CVE-2026-120758)

Solution

Update the hdf5 library and its related packages to version 1.14.5+repack-3+e19 or later.
