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

medium Tenable Cloud Security Plugin ID 478409

Description

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

 - HDF5 through 2.2.0 contains an out-of-bounds read vulnerability in H5Z__filter_szip() in src/H5Zszip.c.
 When decoding a szip-compressed chunk, the function subtracts the 4-byte uncompressed-length header from
 the chunk length without first verifying that the chunk is at least 4 bytes long. A truncated or corrupted
 chunk shorter than the header causes the length calculation to wrap around to a very large value, and the
 decompressor reads far past the end of the chunk buffer. An attacker who can get a user or application to
 read a dataset from a crafted HDF5 file can cause a denial of service. Only builds with szip support
 (libaec or the szip library) are affected. (CVE-2026-120755)

Solution

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