Security Bulletin
This security bulletin contains one low risk vulnerability.
EUVDB-ID: #VU66551
Risk: Low
CVSSv4.0: 1.7 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2021-3979
CWE-ID:
CWE-327 - Use of a Broken or Risky Cryptographic Algorithm
Exploit availability: No
DescriptionThe 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.
Update the affected package ceph to the latest version.
