Rocky Linux 9.6 [TuxCare] Security Update: glib2 / glib2-devel / glib2-doc / glib2-static / glib2-tests (ALMALINUX9.6:CLSA-2026:1787154316)

medium Nessus Plugin ID 361309

Synopsis

The Rocky Linux host is missing one or more security updates.

Description

The Rocky Linux 9.6 host has packages installed that are affected by a vulnerability as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1787154316 advisory.

 - 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)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages based on the guidance in TuxCare advisory ALMALINUX9.6:CLSA-2026:1787154316.
