Title: Microsoft Windows NT 4.0 Networking Mutex DoS Vulnerability
Severity: LOW
Description:
Mutex is an object of Windows NT 4.0 which allow multiple threads to synchronize access to shared resources. When a network resource (program or file etc.) is started, a Mutex is created and is locked by the thread. If other threads attempt to access the resource, the system will queue the thread and will gain control(lock) once the Mutex is available.
Microsoft Windows NT 4.0 is subject to a denial of service due to the implementation of incorrect permissions in a Networking Mutex object (Winsock2ProtocolCatalogMutex). The everyone group has full control by default, a local user can modify the object on a networked machine and cause a denial of network connectivity.
A restart of the machine would be required in order to gain normal functionality.
