"The remote Rocky Linux 8 host has packages installed that are affected by a vulnerability as referenced in the
RLSA-2024:1646 advisory.

  - A memory leak flaw was found in Golang in the RSA encrypting/decrypting code, which might lead to a
    resource exhaustion vulnerability using attacker-controlled inputs. The memory leak happens in
    github.com/golang-fips/openssl/openssl/rsa.go#L113. The objects leaked are pkey and ctx. That function
    uses named return parameters to free pkey and ctx if there is an error initializing the context or
    setting the different properties. All return statements related to error cases follow the return nil,
    nil, fail(...) pattern, meaning that pkey and ctx will be nil inside the deferred function that should
    free them. (CVE-2024-1394)

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