A flaw was found in NetworkManager. This local privilege escalation vulnerability exists in NetworkManager's dhclient backend when processing malformed Manufacturer Usage Description (MUD) URLs. A local user can exploit this flaw to escalate privileges by triggering a script via a crafted MUD URL, provided an administrator has explicitly configured NetworkManager to use dhclient. This issue does not affect default configurations of NetworkManager.
