This indicates a attack attempt to exploit an ASLR bypass vulnerability in Microsoft Office.
The vulnerability could allow attack to bypass ASLR which helps prevent an attacker from leveraging data at predictable locations. Please note ASLR bypass by itself does not allow arbitrary code execution. However, an attacker could use this vulnerability in conjunction with another vulnerability, such as a remote code execution vulnerability that could take advantage of the ASLR bypass to run arbitrary code.
