CVE-2026-15588Gdbusserver: glib2: gdbusserver pre-authentication dos via unbounded sasl line buffering

Red Hat Red Hat Enterprise Linux 10; Red Hat Red Hat Enterprise Linux 10.0 Extended Update Support; Red Hat Red Hat Enterprise Linux 7 Extended Lifecycle Suppo… Publicada: (hace 3 meses)

Descripción

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.

Debilidad (CWE): CWE-770
