The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:5160 advisory.
golang: net/http: limit growth of header canonicalization cache (CVE-2021-44716)
golang: syscall: don’t close fd 0 on ForkExec error (CVE-2021-44717)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
