The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:3319 advisory.

  - The ScalarMult and ScalarBaseMult methods of the P256 Curve may return an incorrect result if called with     some specific unreduced scalars (a scalar larger than the order of the curve). This does not impact usages     of crypto/ecdsa or crypto/ecdh. (CVE-2023-24532)

  - HTTP and MIME header parsing can allocate large amounts of memory, even when parsing small inputs,     potentially leading to a denial of service. Certain unusual patterns of input data can cause the common     function used to parse HTTP and MIME headers to allocate substantially more memory than required to hold     the parsed headers. An attacker can exploit this behavior to cause an HTTP server to allocate large     amounts of memory from a small request, potentially leading to memory exhaustion and a denial of service.
    With fix, header parsing now correctly allocates only the memory required to hold parsed headers.
    (CVE-2023-24534)

  - Multipart form parsing can consume large amounts of CPU and memory when processing form inputs containing     very large numbers of parts. This stems from several causes: 1. mime/multipart.Reader.ReadForm limits the     total memory a parsed multipart form can consume. ReadForm can undercount the amount of memory consumed,     leading it to accept larger inputs than intended. 2. Limiting total memory does not account for increased     pressure on the garbage collector from large numbers of small allocations in forms with many parts. 3.
    ReadForm can allocate a large number of short-lived buffers, further increasing pressure on the garbage     collector. The combination of these factors can permit an attacker to cause an program that parses     multipart forms to consume large amounts of CPU and memory, potentially resulting in a denial of service.
    This affects programs that use mime/multipart.Reader.ReadForm, as well as form parsing in the net/http     package with the Request methods FormFile, FormValue, ParseMultipartForm, and PostFormValue. With fix,     ReadForm now does a better job of estimating the memory consumption of parsed forms, and performs many     fewer short-lived allocations. In addition, the fixed mime/multipart.Reader imposes the following limits     on the size of parsed forms: 1. Forms parsed with ReadForm may contain no more than 1000 parts. This limit     may be adjusted with the environment variable GODEBUG=multipartmaxparts=. 2. Form parts parsed with     NextPart and NextRawPart may contain no more than 10,000 header fields. In addition, forms parsed with     ReadForm may contain no more than 10,000 header fields across all parts. This limit may be adjusted with     the environment variable GODEBUG=multipartmaxheaders=. (CVE-2023-24536)

  - Calling any of the Parse functions on Go source code which contains //line directives with very large line     numbers can cause an infinite loop due to integer overflow. (CVE-2023-24537)

  - Templates do not properly consider backticks (`) as Javascript string delimiters, and do not escape them     as expected. Backticks are used, since ES6, for JS template literals. If a template contains a Go template     action within a Javascript template literal, the contents of the action can be used to terminate the     literal, injecting arbitrary Javascript code into the Go template. As ES6 template literals are rather     complex, and themselves can do string interpolation, the decision was made to simply disallow Go template     actions from being used inside of them (e.g. var a = {{.}}), since there is no obviously safe way to     allow this behavior. This takes the same approach as github.com/google/safehtml. With fix, Template.Parse     returns an Error when it encounters templates like this, with an ErrorCode of value 12. This ErrorCode is     currently unexported, but will be exported in the release of Go 1.21. Users who rely on the previous     behavior can re-enable it using the GODEBUG flag jstmpllitinterp=1, with the caveat that backticks will     now be escaped. This should be used with caution. (CVE-2023-24538)

  - Angle brackets (<>) are not considered dangerous characters when inserted into CSS contexts. Templates     containing multiple actions separated by a '/' character can result in unexpectedly closing the CSS     context and allowing for injection of unexpected HTML, if executed with untrusted input. (CVE-2023-24539)

  - Not all valid JavaScript whitespace characters are considered to be whitespace. Templates containing     whitespace characters outside of the character set \t\n\f\r\u0020\u2028\u2029 in JavaScript contexts     that also contain actions may not be properly sanitized during execution. (CVE-2023-24540)

  - Templates containing actions in unquoted HTML attributes (e.g. attr={{.}}) executed with empty input can     result in output with unexpected results when parsed due to HTML normalization rules. This may allow     injection of arbitrary attributes into tags. (CVE-2023-29400)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
