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

  - xrdp is an open source RDP server. Versions 0.10.6 and prior contain a vulnerability concerning the     processing of Client Control PDUs. During the RDP connection sequence, the parser does not perform     sufficient length validation before reading specific data fields from the network stream. A remote,     unauthenticated attacker could potentially exploit this flaw by sending a specially crafted, truncated     Client Control PDU. Due to missing bounds checks, the xrdp process may perform out-of-bounds memory reads,     which can result in the termination of the service (Denial of Service). However, since xrdp forks a new     process for each connection by default, an out-of-bounds read causing a process crash is unlikely to bring     down the entire xrdp service.This issue has been fixed in version 0.10.6.1. (CVE-2026-55645)

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

The remote Fedora 43 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-bd0a75766f advisory.
