The remote Red Hat Enterprise Linux CoreOS 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:1897 advisory.

  - An attacker may cause an HTTP/2 endpoint to read arbitrary amounts of header data by sending an excessive     number of CONTINUATION frames. Maintaining HPACK state requires parsing and processing all HEADERS and     CONTINUATION frames on a connection. When a request's headers exceed MaxHeaderBytes, no memory is     allocated to store the excess headers, but they are still parsed. This permits an attacker to cause an     HTTP/2 endpoint to read arbitrary amounts of header data, all associated with a request which is going to     be rejected. These headers can include Huffman-encoded data which is significantly more expensive for the     receiver to decode than for an attacker to send. The fix sets a limit on the amount of excess header     frames we will process before closing a connection. (CVE-2023-45288)

  - 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 these issues but has instead relied only on the application's self-reported version number.
