During installation, the installers of the affected products unnecessarily grant default DCOM permissions to the administrator account of the affected products. Users with that administrator accounts can locally or remotely launch and operate DCOM objects that should require UAC elevation. As a result, the attacker may disclose, tamper with, destroy, or delete internal information, or cause the affected system to enter a denial-of-service (DoS) condition.
