The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the fee67ad5-a05e-11f1-ad2b-40b034429ecf advisory.

    rsync project reports:
    This release fixes 33 security issues found during a focused audit of rsync's path           handling and daemon protocol, a companion daemon-protocol fuzzing pass, and reports               from external researchers -- plus several robustness hardenings. CVE IDs were assigned               by VulnCheck (CNA); the precise introduced in version ranges accompany each advisory,               and many are much narrower than everything before 3.5.0. Every fix ships with a               regression test in the test suite that fails on the unfixed tree.

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

  - rsync before 3.5.0 contains a path confinement bypass vulnerability that allows remote clients to escape     the intended inner-module root confinement by constructing paths that resolve outside the chroot boundary     when the module root contains a /./ boundary marker. Attackers can exploit improper handling of the /./     notation or forge delta-basis transfers referencing xname paths that cross the /./ boundary to gain     unauthorized read or write access to files outside the module's subtree. (CVE-2026-53793)

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