Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

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

  - xdg-dbus-proxy is a filtering proxy for D-Bus connections. Prior to 0.1.7, a policy parser vulnerability     allows bypassing eavesdrop restrictions. The proxy checks for eavesdrop=true in policy rules but fails to     handle eavesdrop ='true' (with a space before the equals sign) and similar cases. Clients can intercept     D-Bus messages they should not have access to. This vulnerability is fixed in 0.1.7. (CVE-2026-34080)

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

The remote Debian 13 host has packages installed that are affected by a vulnerability as referenced in the dsa-6209 advisory.
