AI-suggested

Red Hat has released updated Unbound packages for RHEL 8 and 9 that address this vulnerability. The fix involves adding a new configuration file (/etc/unbound/conf.d/remote-control.conf) that restricts control access to a Unix socket and enables certificate-based authentication (control-use-cert: yes). Users should update to the patched versions provided by Red Hat advisories RHSA-2024:1750 and RHSA-2024:1751. To verify if a system is vulnerable, run "unbound-control status | grep control"; output containing "control(ssl)" or "control(namedpipe)" indicates a non-vulnerable configuration. If only "control" is returned, the system is vulnerable and should be fixed by including the new configuration file or adding the directives to custom control configuration files. Follow Red Hat's update instructions at https://access.redhat.com/articles/11258.

Description

A vulnerability was found in Unbound due to incorrect default permissions, allowing any process outside the unbound group to modify the unbound runtime configuration. If a process can connect over localhost to port 8953, it can alter the configuration of unbound.service. This flaw allows an unprivileged attacker to manipulate a running instance, potentially altering forwarders, allowing them to track all queries forwarded by the local resolver, and, in some cases, disrupting resolving altogether.
