The specific flaw exists within OfcPIPC_64x.dll. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of SYSTEM.
