Description

This security bulletin contains information about 6 vulnerabilities.


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

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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.


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

CWE-ID: CWE-347 - Improper Verification of Cryptographic Signature

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


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

CWE-ID: CWE-254 - Security Features

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


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

CWE-ID: CWE-399 - Resource Management Errors

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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.


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

CWE-ID: CWE-399 - Resource Management Errors

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


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.


6) NULL pointer dereference (CVE-ID: CVE-2024-0727)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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

The vulnerability exists due to a NULL pointer dereference error when processing fields in the PKCS12 certificate. A remote attacker can pass specially crafted certificate to the server and perform a denial of service (DoS) attack.
