An issue was discovered in HDF5 through 1.12.0. A heap-based buffer over-read exists in the function H5O__layout_decode() located in H5Olayout.c. It allows an attacker to cause Denial of Service.
Created hdf5 tracking bugs for this issue:
Affects: epel-all [bug 1827481]
Affects: fedora-all [bug 1827480]
HDF5 is an unused part of RHOSP, it is a loose requirement and included but not used.
As OpenShift 4.3 included OpenStack components briefly, HDF5 was present.
As such marking OpenStack and OpenShift as affected/wontfix.
This bug is now closed. Further updates for individual products will be reflected on the CVE page(s):
HDF5 is included as part of a loose dependency trail from python3-hardware package. There is a very low likelihood that an attacker would be able to exploit this vulnerability in a meaningful way in both OpenShift and OpenStack
In OpenShift 4.3, hdf5 is included in the container openshift/ironic-hardware-inventory-recorder-image, the dependency tail is: python3-hardware -> python3-pandas -> python3-tables -> hdf5
