Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) Security features bypass (CVE-ID: CVE-2023-0466)

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to an error within the X509_VERIFY_PARAM_add0_policy() function, which does not perform the certificate policy check despite being implicitly enabled. A remote attacker can bypass expected security restrictions and perform MitM attack.


2) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2023-0465)

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to an error when validating certificate policies in leaf certificates. A remote attacker that controls a malicious CA server can issue a certificate that will be validated by the application.


3) Resource management error (CVE-ID: CVE-2023-3446)

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.


4) Input validation error (CVE-ID: CVE-2023-4807)

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

The vulnerability exists due to insufficient validation of user-supplied input within the POLY1305 MAC (message authentication code) implementation. A remote attacker can send specially crafted input to the application and corrupt MM registers on Windows 64 platform, resulting in a denial of service condition.


5) Resource management error (CVE-ID: CVE-2023-3817)

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 application when checking the long DH keys. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
