"The remote Oracle Linux 9 host has packages installed that are affected by a vulnerability as referenced in the
ELSA-2023-2523 advisory.
- OpenSSL supports creating a custom cipher via the legacy EVP_CIPHER_meth_new() function and associated
function calls. This function was deprecated in OpenSSL 3.0 and application authors are instead encouraged
to use the new provider mechanism in order to implement custom ciphers. OpenSSL versions 3.0.0 to 3.0.5
incorrectly handle legacy custom ciphers passed to the EVP_EncryptInit_ex2(), EVP_DecryptInit_ex2() and
EVP_CipherInit_ex2() functions (as well as other similarly named encryption and decryption initialisation
functions). Instead of using the custom cipher directly it incorrectly tries to fetch an equivalent cipher
from the available providers. An equivalent cipher is found based on the NID passed to
EVP_CIPHER_meth_new(). This NID is supposed to represent the unique NID for a given cipher. However it is
possible for an application to incorrectly pass NID_undef as this value in the call to
EVP_CIPHER_meth_new(). When NID_undef is used in this way the OpenSSL encryption/decryption initialisation
function will match the NULL cipher as being equivalent and will fetch this from the available providers.
This will succeed if the default provider has been loaded (or if a third party provider has been loaded
that offers this cipher). Using the NULL cipher means that the plaintext is emitted as the ciphertext.
Applications are only affected by this issue if they call EVP_CIPHER_meth_new() using NID_undef and
subsequently use it in a call to an encryption/decryption initialisation function. Applications that only
use SSL/TLS are not impacted by this issue. Fixed in OpenSSL 3.0.6 (Affected 3.0.0-3.0.5). (CVE-2022-3358)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
