Heap-based buffer overflow in Microsoft Office allows an unauthorized attacker to execute code locally.

**Are there any further actions I need to take to be protected from relay attacks?** The security updates released on September 9, 2025 enable support for auditing SMB client compatibility for SMB Server signing as well as SMB Server EPA. This allows customers to assess their environment and identify any potential device or software incompatibility issues before deploying the hardening measures that are already supported by SMB Server. Please see https://support.microsoft.com/help/5066913 for more information.

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to win a race condition.

Concurrent execution using shared resource with improper synchronization ('race condition') in Microsoft Brokering File System allows an authorized attacker to elevate privileges locally.

**What type of information could be disclosed by this vulnerability?** The type of information that could be disclosed if an attacker successfully exploited this vulnerability is sensitive information.
