Technical details

A vulnerability classified as an untrusted pointer dereference (CWE-822) exists in Microsoft Office Word. The flaw occurs when the application improperly handles memory pointers from an untrusted source, which can be manipulated to redirect execution flow. An attacker with local access can exploit this to execute arbitrary code with the privileges of the current user.
