⚠️ A crafty spreadsheet could lead to chaos! This heap-based buffer overflow in multiple versions of Microsoft Excel is a sneaky way for remote attackers to execute arbitrary code. 🚨 Think of it like a trusted delivery service accepting a package without checking if it’s labeled correctly — if the contents are malicious, they can wreak havoc before anyone notices! An attacker could execute their own code on your system, potentially leading to data breaches, unauthorized access, and total system control. While exploitation hasn’t been widely reported, the risk remains real and should not be ignored.
