"The version of cloud-hypervisor-cvm / nodejs18 / nodejs installed on the remote CBL Mariner 2.0 host is prior to tested
version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-4603 advisory.

  - Issue summary: Checking excessively long DSA keys or parameters May be very slow. Impact summary:
    Applications that use the functions EVP_PKEY_param_check() or EVP_PKEY_public_check() to check a DSA
    public key or DSA parameters May experience long delays. Where the key or parameters that are being
    checked have been obtained from an untrusted source this May lead to a Denial of Service. The functions
    EVP_PKEY_param_check() or EVP_PKEY_public_check() perform various checks on DSA parameters. Some of those
    computations take a long time if the modulus (`p` parameter) is too large. Trying to use a very large
    modulus is slow and OpenSSL will not allow using public keys with a modulus which is over 10,000 bits in
    length for signature verification. However the key and parameter check functions do not limit the modulus
    size when performing the checks. An application that calls EVP_PKEY_param_check() or
    EVP_PKEY_public_check() and supplies a key or parameters obtained from an untrusted source could be
    vulnerable to a Denial of Service attack. These functions are not called by OpenSSL itself on untrusted
    DSA keys so only applications that directly call these functions May be vulnerable. Also vulnerable are
    the OpenSSL pkey and pkeyparam command line applications when using the `-check` option. The OpenSSL
    SSL/TLS implementation is not affected by this issue. The OpenSSL 3.0 and 3.1 FIPS providers are affected
    by this issue. (CVE-2024-4603)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
