[原文]Buffer overflow in Ce/Ceterm (aka ARPUS/Ce) 2.5.4 and earlier may allow local users to gain privileges via a long (1) XAPPLRESLANGPATH or (2) XAPPLRESDIR environment variable, or (3) command line argument.


[CNNVD]ARPUS/Ce setuid缓冲区溢出和文件覆盖漏洞(CNNVD-200505-878)

        Ce/Ceterm(也被称为ARPUS/Ce)是一款集成的ascii文本编辑器和基于X-based终端模拟器。
        Ce启动是会检查是否是ceterm。如果不是的话就会立即丢弃setuid,如果是ceterm的话就会在打开伪终端时丢弃setuid。但是Ce没能正确的处理丢弃权限,这样攻击者就可能滥用应用程序。

16438
Ce/Ceterm Multiple Local Overflows
Local Access Required Input Manipulation
Loss of Integrity
Exploit Public

- 漏洞描述

Multiple local overflows exist in Arpus/Ce. The application fails to perform proper bounds checking resulting in a buffer overflow. With a specially crafted request containing either an overly long 'XAPPLRESLANGPATH' or 'XAPPLRESDIR' environment variable, or command line argument, a malicious user can cause arbitrary code execution resulting in a loss of integrity.

- 不受影响的程序版本

ARPUS Ce/Ceterm 2.6

- 漏洞讨论

ARPUS Ce/Ceterm is prone to a buffer overflow vulnerability when processing command line arguments. In many cases, the application runs with the setuid bit set, allowing arbitrary code to be executed with root privileges.

Ce/Ceterm will run as setuid root in many cases. Versions of Ce/Ceterm from 2.6 onwards do not need to be setuid in order to function properly.

- 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 &lt;mailto:vuldb@securityfocus.com&gt;.

- 解决方案

The vendor has reported that version 2.6 and later of Ce/Ceterm no longer require the setuid bit to be set.
