漏洞描述
中文描述:
Red Hat Enterprise Linux (RHEL) 3版本的内核状态下的NFS客户端,当一个文件系统通过noacl操作加载(mounted)时，检查许可权限通过vfs_permission (mode bits) data的开放系统调用权限优先于NFS ACCESS访问调用服务，使本地客户进程从服务器开放访问中获得假的成功状况，并可能获得服务器文件许可的敏感信息，比如在一个root_squash环境中。
英文描述:
The NFS client implementation in the kernel in Red Hat Enterprise Linux (RHEL) 3, when a filesystem is mounted with the noacl option, checks permissions for the open system call via vfs_permission (mode bits) data rather than an NFS ACCESS call to the server, which allows local client processes to obtain a false success status from open calls that the server would deny, and possibly obtain sensitive information about file permissions on the server, as demonstrated in a root_squash environment. NOTE: it is uncertain whether any scenarios involving this issue cross privilege boundaries.
