Microsoft Patches Two Dozen RCE Flaws in Office

Microsoft released emergency patches addressing over 30 vulnerabilities, including two dozen high-severity remote code execution flaws in its Office suite, many exploitable simply through the Preview Pane without requiring the user to open a malicious document. The root cause of most RCEs is buffer overflow weaknesses, a well-understood and preventable class of vulnerability. This matters because Office is ubiquitous across enterprises, making unpatched systems an extremely broad and attractive attack surface. Although none of these flaws were exploited as zero-days at the time of disclosure, the window between patch release and deployment is a critical period of elevated risk. Organizations that delay patching or lack visibility into their software inventory are most exposed during this window.
