# Vulnerability: Remote Kernel Heap Overflow in Windows Server NFSv3
## CVE Details
- CVE ID: CVE-2020-17051
- CVSS Score: N/A (Severity N/A - Title suggests high severity due to kernel heap overflow)
- CWE: N/A
## Affected Systems
- Products: Windows Server (specifically related to the NFSv3 service)
- Versions: N/A (Specific vulnerable Windows versions were not detailed in the context provided)
- Configurations: Systems running the relevant version of Windows Server with the NFSv3 service enabled.
## Vulnerability Description
The vulnerability is described as a **Remote kernel heap overflow** occurring within the **NFSv3 service** on Windows Server. A heap overflow in kernel memory generally suggests an attacker can exploit insufficient bounds checking on memory allocations to corrupt adjacent memory, potentially leading to arbitrary code execution with SYSTEM privileges.
