Omni-NFS Server NFSD.EXE Stack Buffer Overflow Vulnerability

Omni-NFS Server is prone to a stack-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied network data before copying it into an insufficiently sized memory buffer.

Exploiting this issue allows attackers to execute arbitrary machine code in the context of users running the affected application. Failed attempts will likely crash the application, resulting in denial-of-service conditions.

Omni-NFS Server version 5.2 is vulnerable.
