NVD Description

Note: Versions mentioned in the description apply only to the upstream glib2-debuginfo package and not the glib2-debuginfo package as distributed by Rocky-Linux. See How to fix? for Rocky-Linux:9 relevant fixed versions and status.

A denial-of-service and resource exhaustion vulnerability exists within the GDBus component of GLib. The gdbusauth authentication mechanism fails to enforce proper length limitations on data lines read from a client. An unauthenticated local or remote attacker can exploit this lack of input validation by sending excessively long streams of data, causing the application to consume massive amounts of system memory and CPU, potentially leading to a crash or system hang.
