EUVDB-ID: #VU66551

Risk: Low

CVSSv3.1: 4 [CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-3979

CWE-ID: CWE-327 - Use of a Broken or Risky Cryptographic Algorithm

Exploit availability: No

Description

The vulnerability allows an attacker to gain access to sensitive information.

The vulnerability exists due to Ceph volume does not the honour osd_dmcrypt_key_size, resulting in the key length is being incorrectly passed in an encryption algorithm to create a non random key. An attacker with physical access to encrypted device can decrypt data and gain access to sensitive information.

Mitigation

Update the affected package ceph to the latest version.
