Name of the Vulnerable Software and Affected Versions xdg-dbus-proxy versions prior to 0.1.7

Description xdg-dbus-proxy is a filtering proxy for D-Bus connections. A policy parser issue allows bypassing eavesdrop restrictions. The proxy incorrectly handles variations in the 'eavesdrop' policy rule format, such as including a space before the equals sign (e.g., 'eavesdrop ='true''). This allows clients to intercept D-Bus messages they are not authorized to access.

Recommendations Update to version 0.1.7 or later.
