[CNNVD]SGI IRIX rpc.mountd加载未明文件访问漏洞(CNNVD-200509-184)

        IRIX是一款由SGI公司开发和维护的商业性质UNIX操作系统。
        SGI IRIX中存在未明的文件访问漏洞,远程攻击者可能利用此漏洞非授权限访问文件。起因是NFS服务器无法正确地强制客户端机器上的权限。这个漏洞允许客户端机器获取管理员允许范围以外的访问。在某些环境下,NFS客户端还可以获取对主读(read-mostly)网络共享中文件不恰当的读写访问。

- 漏洞讨论

SGI IRIX is susceptible to an unspecified file access vulnerability. This issue is due to a failure of the NFS server to properly enforce privileges on client computers.

This issue allows client computers to gain access beyond that which the administrator has allowed. In certain unspecified circumstances, NFS clients may gain inappropriate read-write access to files contained in read-mostly network shares.

SGI IRIX versions 6.5.25 through 6.5.27 are vulnerable. Previous versions may also be affected.

- 漏洞利用

An exploit is not required.

- 解决方案

The vendor has released security advisory 20050601-01-P, along with fixes to address this issue. Please see the referenced advisory for further information.
