The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:3623 advisory.
c-ares: Missing input validation of host names may lead to domain hijacking (CVE-2021-3672)
nodejs: Use-after-free on close http2 on stream canceling (CVE-2021-22930, CVE-2021-22940)
nodejs: Improper handling of untypical characters in domain names (CVE-2021-22931)
nodejs: Incomplete validation of tls rejectUnauthorized parameter (CVE-2021-22939)
nodejs-path-parse: ReDoS via splitDeviceRe, splitTailRe and splitPathRe (CVE-2021-23343)
nodejs-tar: Insufficient symlink protection allowing arbitrary file creation and overwrite (CVE-2021-32803)
nodejs-tar: Insufficient absolute path sanitization allowing arbitrary file creation and overwrite (CVE-2021-32804)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
