Detailed Description The version of OpenSSL installed on the remote host is prior to 1.1.1t. It is, therefore, affected by multiple vulnerabilities as referenced in the 1.1.1t advisory.

- There is a type confusion vulnerability relating to X.400 address processing inside an X.509 GeneralName.X.400 addresses were parsed as an ASN1_STRING but the public structure definition for GENERAL_NAME incorrectly specified the type of the x400Address field as ASN1_TYPE. (CVE-2023-0286)

- The public API function BIO_new_NDEF is a helper function used for streaming ASN.1 data via a BIO. It is primarily used internally to OpenSSL to support the SMIME, CMS and PKCS7 streaming capabilities, but may also be called directly by end user applications. (CVE-2023-0215)

- The function PEM_read_bio_ex() reads a PEM file from a BIO and parses and decodes the name (e.g.CERTIFICATE), any header data and the payload data. If the function succeeds then the name_out, header and data arguments are populated with pointers to buffers containing the relevant decoded data.(CVE-2022-4450)

- A timing based side channel exists in the OpenSSL RSA Decryption implementation which could be sufficient to recover a plaintext across a network in a Bleichenbacher style attack. To achieve a successful decryption an attacker would have to be able to send a very large number of trial messages for decryption.(CVE-2022-4304)
