Descriptions

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.

Se encontró una vulnerabilidad en Unbound debido a permisos predeterminados incorrectos, lo que permite que cualquier proceso fuera del grupo independiente modifique la configuración del tiempo de ejecución independiente. Si un proceso puede conectarse a través de localhost al puerto 8953, puede alterar la configuración de unbound.service. Esta falla permite que un atacante sin privilegios manipule una instancia en ejecución, alterando potencialmente a los reenviadores, permitiéndoles rastrear todas las consultas enviadas por el solucionador local y, en algunos casos, interrumpiendo la resolución por completo.
