Technical details
A use-after-free vulnerability in Microsoft Office PowerPoint permits remote code execution when processing malicious presentation files. The vulnerability exists in PowerPoint's memory management, where a freed object is accessed in an unsafe manner, allowing an attacker to overwrite memory and achieve arbitrary code execution. Attack vectors include network-based delivery of malicious Office files, with no authentication required but typically requiring user interaction to open the file. An attacker can exploit this to gain code execution in the context of the user running PowerPoint. Patches are available from Microsoft.
