The version of cloud-hypervisor-cvm / edk2 / hvloader / nodejs / nodejs18 / openssl installed on the remote Azure Linux 3.0 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.
