Description
This security bulletin contains information about 3 vulnerabilities.
1) HTTP response splitting (CVE-ID: CVE-2021-3524)
CWE-ID: CWE-113 - Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to perform HTTP splitting attacks.
The vulnerability exists due to software does not correctly process CRLF character sequences. A remote attacker can send specially crafted request containing CRLF sequence and make the application to send a split HTTP response.
Successful exploitation of the vulnerability may allow an attacker perform cache poisoning attack.
2) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2021-3979)
CWE-ID: CWE-327 - Use of a Broken or Risky Cryptographic Algorithm
CVSSv4: 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
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.
3) Covert Timing Channel (CVE-ID: CVE-2020-25658)
CWE-ID: CWE-385 - Covert Timing Channel
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to a covert timing channel. A remote attacker can perform Bleichenbacher timing attack and decrypt parts of data via the RSA decryption API.
