Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:2848 advisory.

  • nghttp2: overly large SETTINGS frames can lead to DoS (CVE-2020-11080)

  • nodejs-minimist: prototype pollution allows adding or modifying properties of Object.prototype using a constructor or proto payload (CVE-2020-7598)

  • nodejs: memory corruption in napi_get_value_string_* functions (CVE-2020-8174)

Note that Nessus has not tested for this issue but has instead relied only on the application
