Echo: hdf5: security update to 1.14.5+repack-3+e18

medium Tenable Self-Hosted Container Security Plugin ID 478407

Description

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

 - HDF5 through 2.2.0 contains a heap buffer over-read vulnerability in H5O__chunk_deserialize() in
 src/H5Ocache.c. When decoding object header messages, the declared message size is checked against the end
 of the chunk image before the remainder of the message header (flags, and for version 2 object headers,
 the optional creation index) has been decoded. Because the message body begins after these fields, a
 message can start up to four bytes further into the chunk than the size check accounts for. A crafted HDF5
 file can declare a message size that passes the check but extends past the end of the chunk image, causing
 the message’s decode callback, for example H5O__mtime_new_decode() in src/H5Omtime.c, to read beyond the
 heap allocation. The flaw is reachable during H5Fopen() on a crafted file. An attacker who can get a user
 or application to open a malicious file can cause a denial of service or limited disclosure of process
 memory. (CVE-2026-120756)

Solution

Update the hdf5 library and its related packages to version 1.14.5+repack-3+e18 or later.
