AlmaLinux 9.2 [TuxCare] Security Update: xdg-dbus-proxy (ALMALINUX9.2:CLSA-2026:1789132992)

medium Nessus Plugin ID 352165

Synopsis

The AlmaLinux host is missing one or more security updates.

Description

The AlmaLinux 9.2 host has a package installed that is affected by a vulnerability as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1789132992 advisory.

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

Solution

Update the affected xdg-dbus-proxy package based on the guidance in TuxCare advisory ALMALINUX9.2:CLSA-2026:1789132992.
