Asymmetric denial of service In glib2.0
Description
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.
Mitigation
Update Impact
Minimal update. May introduce new vulnerabilities or breaking changes.
