The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A flaw was found in Undertow where malformed client requests can trigger server-side stream resets without     triggering abuse counters. This issue, referred to as the MadeYouReset attack, allows malicious clients     to induce excessive server workload by repeatedly causing server-side stream aborts. While not a protocol     bug, this highlights a common implementation weakness that can be exploited to cause a denial of service     (DoS). (CVE-2025-9784)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:4917 advisory.
