[原文]rquotad in nfs-utils (rquota_server.c) before 1.0.6-r6 on 64-bit architectures does not properly perform an integer conversion, which leads to a stack-based buffer overflow and allows remote attackers to execute arbitrary code via a crafted NFS request.


[CNNVD]nfs-utils rquotad 缓冲区溢出漏洞(CNNVD-200501-040)

        nfs-utils是网络文件系统(NFS)工具包。
        1.0.6-r6之前版本的64位架构nfs-utils中的rquotad不能正常执行整数转换,存在栈缓冲区溢出。
        远程攻击者可以通过特制的NFS请求,利用此漏洞执行任意代码。

- 漏洞讨论

A remote buffer overflow reportedly affects the disk quota functionality of the Linux NFS utilities. This issue is due to the software's failure to properly validate the length of user-supplied strings before copying them into static process buffers.

An attacker may leverage this issue to execute arbitrary code on an affected computer with superuser privileges. This may be exploited to gain unauthorized access or privilege escalation.

- 漏洞利用

Currently we are not aware of any exploits for this issue. If you feel we are in error or are aware of more recent information, please mail us at: vuldb@securityfocus.com <mailto:vuldb@securityfocus.com>.
