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

medium Tenable Cloud Security Plugin ID 478406

Description

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

 - HDF5 through 2.2.0 contains an uninitialized memory read vulnerability in H5Z__filter_scaleoffset() in
 src/H5Zscaleoffset.c. The decode path validates reads against the allocated size of the chunk buffer
 rather than the number of bytes actually read from the file. Because H5D__chunk_lock() deliberately sizes
 filtered chunk buffers to the larger of the stored and unfiltered chunk sizes and fills only the stored
 bytes, a truncated chunk passes these bounds checks and is decompressed from the uninitialized remainder
 of the allocation. Unrelated heap contents are then returned to the caller as dataset data. Because the
 reads remain within the allocation, the issue is not detected by AddressSanitizer. An attacker who can get
 a user or application to read a dataset from a crafted HDF5 file can cause disclosure of process memory.
 This issue exists because of an incomplete fix for CVE-2026-19029. (CVE-2026-120754)

Solution

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