Doc Text:
A Key Length flaw was found in Red Hat Ceph Storage. An attacker can exploit the fact that the key length is incorrectly passed in an encryption algorithm to create a non random key, which is weaker and can be exploited for loss of confidentiality and integrity on encrypted disks.

Description Sage McTaggart 2021-11-30 20:38:57 UTC
Upon running 'cryptsetup luksDump' on encrypted devices created with ceph-volume, it was noticed that the key length is inaccurate. This is due to a bug in ceph_volume/util/encryption.py. It does not pass the correct key size to the following format and open operations.
