1) Improper Authentication

EUVDB-ID: #VU78265

Risk: Low

CVSSv3.1: 3.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-2975

CWE-ID: CWE-287 - Improper Authentication

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to an error in the AES-SIV cipher implementation when authenticating empty data entries via the EVP_EncryptUpdate() and EVP_CipherUpdate() functions. A remote attacker can bypass authentication process and impact application's integrity.

Mitigation

Update the affected package openssl-3 to the latest version.

2) Resource management error

EUVDB-ID: #VU78463

Risk: Medium

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-3446

CWE-ID: CWE-399 - Resource Management Errors

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper management of internal resources within the DH_check(), DH_check_ex() and EVP_PKEY_param_check() function when processing a DH key or DH parameters. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.

Mitigation

Update the affected package openssl-3 to the latest version.
