Official description
Allocation of Resources Without Limits and Throttling and Sensitive Information in Resource Not Removed Before Reuse in the ASUS System Control Interface driver and ASUS Business Manager allow a local administrator to disclose sensitive information via crafted IOCTL requests, which, in severe cases, may lead to a Denial of Service (DoS) on the system. Refer to the ' Security Update for ASUS System Control Interface ' section on the ASUS Security Advisory for more information.

The underlying weakness: Sensitive Information in Resource Not Removed Before Reuse
The product releases a resource such as memory or a file so that it can be made available for reuse, but it does not clear or zeroize the information contained in the resource before the product performs a critical state transition or makes the resource available for reuse by other entities.
How developers prevent this class of flaw
- During critical state transitions, information not needed in the next state should be removed or overwritten with fixed patterns (such as all 0's) or random data, before the transition to the next state.
- Be careful using vfork() and fork() in security sensitive code. The process state will not be cleaned up and will contain traces of data from past use.
