Description Pedro Sampaio 2020-04-24 03:23:20 UTC
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. 



Comment 1 Pedro Sampaio 2020-04-24 03:26:09 UTC
Created hdf5 tracking bugs for this issue:

Affects: epel-all [bug 1827481]
Affects: fedora-all [bug 1827480]

Comment 3 Mark Cooper 2020-04-29 04:22:12 UTC
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):


Comment 6 Joshua Padman 2020-04-30 00:38:36 UTC

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
