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.

Affected: openEuler:20.03-LTS-SP1: ceph, openEuler:20.03-LTS-SP2: ceph, openEuler:20.03-LTS-SP3: ceph

User space components of the Ceph file system. Security Fix(es): The key length for encrypted devices created using ceph-volume is incorrect. This is due to a bug in ceph_volume/util/encryption.py, where upon writing a key using osd_dmcrypt_key_size it does not pass the key size to the format and open operations following. The default key is then applied in cryptsetup. All versions since Luminous are assumed affected.(CVE-2021-3979)

gateway: radosgw: CRLF injection ceph: RGW unauthenticated denial of service ceph: Ceph volume does not honour osd_dmcrypt_key_size

Affected: Ubuntu:18.04:LTS: ceph, Ubuntu:20.04:LTS: ceph
