Exploitability

CWE

KEV

CWE ID	Description
CWE-416	The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Attack-Flow Graph

Executive Summary

This is a use-after-free vulnerability in Microsoft Office PowerPoint. It allows an unauthorized attacker to execute arbitrary code over a network by exploiting a memory management flaw.

Detection Guidance

Detection typically involves monitoring for unusual PowerPoint file activity or crashes. Check for recent PowerPoint crashes or unexpected processes spawned by PowerPoint. Use tools like Process Monitor to track PowerPoint-related memory access patterns. Ensure your antivirus or EDR solutions are updated to detect exploits targeting this vulnerability.

Impact Analysis

An attacker could exploit this to run malicious code on your system, potentially stealing data, installing malware, or taking control of your computer if you open a specially crafted PowerPoint file.

Compliance Impact

This vulnerability allows remote code execution via a use-after-free flaw in Microsoft Office PowerPoint. Such vulnerabilities can lead to unauthorized access, data breaches, or malware execution, which may violate compliance requirements under GDPR (data protection) and HIPAA (health data security) by exposing sensitive information or disrupting systems.

Mitigation Strategies

Apply the latest security updates from Microsoft for PowerPoint and Office products. Disable PowerPoint file opening from untrusted sources and restrict network access to Office applications until patched.
