The most likely threat is from a local user, which may be possible depending on the configuration of the service and the format of parameters that it expects. While a remote attack is possible if the application is configured to read GVariants over a network connection, this is not the default configuration which makes the likelihood low. Because the most widely available attack vector is local and the consequences are limited to denial of service, Red Hat Product Security rates the impact as Low. This issue has been addressed in the following products: Red Hat Enterprise Linux 9 Via RHSA-2024:2528 https://access.redhat.com/errata/RHSA-2024:2528 |
