Description
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to arbitrary write in the open document format parser, while trying to null-terminate a string. A remote attacker can trick the victim into opening a specially crafted Word document, pass an untrusted value as a length to a constructor, miscalculate a length and then use it to calculate the position to write a null byte, trigger memory corruption and execute arbitrary code under the context of the application.
Successful exploitation of the vulnerability may result in system compromise.
