"The remote Red Hat Enterprise Linux CoreOS 4 host has packages installed that are affected by multiple vulnerabilities
as referenced in the RHSA-2023:3613 advisory.

  - In net/http in Go before 1.18.6 and 1.19.x before 1.19.1, attackers can cause a denial of service because
    an HTTP/2 connection can hang during closing if shutdown were preempted by a fatal error. (CVE-2022-27664)

  - Reader.Read does not set a limit on the maximum size of file headers. A maliciously crafted archive could
    cause Read to allocate unbounded amounts of memory, potentially causing resource exhaustion or panics.
    After fix, Reader.Read limits the maximum size of header blocks to 1 MiB. (CVE-2022-2879)

  - Requests forwarded by ReverseProxy include the raw query parameters from the inbound request, including
    unparsable parameters rejected by net/http. This could permit query parameter smuggling when a Go proxy
    forwards a parameter with an unparsable value. After fix, ReverseProxy sanitizes the query parameters in
    the forwarded query when the outbound request's Form field is set after the ReverseProxy. Director
    function returns, indicating that the proxy has parsed the query parameters. Proxies which do not parse
    query parameters continue to forward the original query parameters unchanged. (CVE-2022-2880)

  - An attacker may cause a denial of service by crafting an Accept-Language header which ParseAcceptLanguage
    will take significant time to parse. (CVE-2022-32149)

  - JoinPath and URL.JoinPath do not remove ../ path elements appended to a relative path. For example,
    JoinPath(https://go.dev, ../go) returns the URL https://go.dev/../go, despite the JoinPath
    documentation stating that ../ path elements are removed from the result. (CVE-2022-32190)

  - Programs which compile regular expressions from untrusted sources may be vulnerable to memory exhaustion
    or denial of service. The parsed regexp representation is linear in the size of the input, but in some
    cases the constant factor can be as high as 40,000, making relatively small regexps consume much larger
    amounts of memory. After fix, each regexp being parsed is limited to a 256 MB memory footprint. Regular
    expressions whose representation would use more space than that are rejected. Normal use of regular
    expressions is unaffected. (CVE-2022-41715)

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