Put simply

Think of it like leaving a dinner party while the pot roast is still cooking. If you forget to turn off the oven, it could ruin the meal — just like how this vulnerability can leave your system vulnerable to attacks if not properly handled. This use-after-free vulnerability arises when Excel mishandles memory during the processing of a crafted calculatedColumnFormula object within an Office document, allowing remote attackers to run malicious code.

What to do

An attacker could exploit this vulnerability to execute arbitrary code on your system, potentially leading to unauthorized access and data breaches. Imagine someone taking control of your Excel — that's not just inconvenient, it's downright scary! To mitigate this issue, ensure that you apply the latest patches for your Excel versions, specifically targeting 2010 SP2, 2013 SP1, and 2016.
