[原文]Buffer overflow in the Xsan Filesystem driver on Mac OS X 10.4.7 and OS X Server 10.4.7 allows local users with Xsan write access, to execute arbitrary code via unspecified vectors related to "processing a path name."

[CNNVD]Apple Mac OS X Xsan Filesystem路径名缓冲区溢出漏洞(CNNVD-200608-321)

        Mac OS X 10.4.7和OS X Server 10.4.7操作系统下的Xsan Filesystem驱动程序存在缓冲区溢出漏洞,有Xsan写权限的本地用户可借助与"处理一个路径名"有关的未明向量执行任意代码。

Apple Mac OS X Xsan Filesystem Path Name Processing Overflow
Local Access Required Input Manipulation
Loss of Integrity
Exploit Unknown

- 漏洞描述

A local overflow exists in Mac OS X. The included Xsan filesystem driver fails to validate path names resulting in a buffer overflow. With a specially crafted pathname, an attacker can cause arbitrary code execution resulting in a loss of integrity.

- 不受影响的程序版本

Apple Xsan 1.4

- 漏洞讨论

Apple Xsan filesystem is prone to a buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied input before copying it into an insufficiently sized buffer.

This issue may allow remote attackers to execute arbitrary machine code with system privileges on computers directly attached to the vulnerable filesystem. Failed exploit attempts will likely crash the system, denying service to legitimate users.
