Echo: glib2.0: security update to 2.84.4-3~deb13u3+e4

medium Tenable Self-Hosted Container Security Plugin ID 459998

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-15588)

Solution

Update the glib2.0 library and its related packages to version 2.84.4-3~deb13u3+e4 or later.
