The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:0079 advisory.

  • golang.org/x/crypto: Keystream loop in amd64 assembly when overflowing 32-bit counter (CVE-2019-11840)

  • python-urllib3: CRLF injection via HTTP request method (CVE-2020-26137)

  • kubernetes: MITM using LoadBalancer or ExternalIPs (CVE-2020-8554)

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