Description

This security bulletin contains information about 7 secuirty vulnerabilities.


1) 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.


2) 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.


3) 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.


4) 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.


5) Resource exhaustion (CVE-ID: CVE-2023-0464)

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

The vulnerability exists due to application does not properly control consumption of internal resources when verifying X.509 certificate chains that include policy constraints. A remote attacker can create a specially crafted certificate to trigger resource exhaustion and perform a denial of service (DoS) attack.


6) Resource management error (CVE-ID: CVE-2023-2650)

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 processing OCSP, PKCS7/SMIME, CMS, CMP/CRMF or TS subsystems with no message size limit. A remote attacker can send specially crafted data to the application and perform a denial of service (DoS) attack.


7) Open redirect (CVE-ID: CVE-2023-41080)

The vulnerability allows a remote attacker to redirect victims to arbitrary URL.

The vulnerability exists due to improper sanitization of user-supplied data, if the ROOT (default) web application is configured to use FORM authentication. A remote attacker can create a link that leads to a trusted website, however, when clicked, redirects the victim to arbitrary domain.

Successful exploitation of this vulnerability may allow a remote attacker to perform a phishing attack and steal potentially sensitive information.
