Detailed vulnerability description
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to uninitialized pointer in the rich text format parser. A remote attacker can trick the victim into opening a specially crafted Word document, cause certain RTF tokens to dereference a pointer that has been uninitialized and then write to it and execute arbitrary code under the context of the application.
Successful exploitation of the vulnerability may result in system compromise.
