Linux NFS Server Pathname Overflow
Remote / Network Access Input Manipulation

- 漏洞描述

A remote overflow exists in NFS Server. The application fails to perform proper bounds checking resulting in a buffer overflow. With a specially crafted request containing an overly long pathname on a read-write mounted NFS directory, a remote attacker can cause arbitrary code execution resulting in a loss of integrity.
