[原文]Multiple buffer overflows in mnews 1.22 and earlier allow (1) a remote NNTP server to execute arbitrary code via long responses, or local users can gain privileges via long command line arguments (2) -f, (3) -n, (4) -D, (5) -M, or (6) -P, or via long environment variables (7) JNAMES or (8) MAILSERVER.


[CNNVD]MNews多个缓冲区溢出漏洞(CNNVD-200210-083)

        
        Mnews是一款基于控制台的邮件和新闻客户端,主要设计用于处理日文和英文字符集,一般以setgid mail方式安装。
        Mnews对命令行参数和环境变量的缓冲边界缺少正确充分检查,可导致本地攻击者进行缓冲区溢出,提升权限。
        Mnews对部分命令选项如'-f'、'-D'、'-M'、'-P'和'-n'的参数数据缺少正确充分的边界缓冲检查,以及对MAILSERVER和JNAMES环境变量参数缺少正确充分的缓冲区边界检查,攻击者可以提供超长字符串作为参数给上述命令行选项或者环境变量,当程序运行时可导致产生缓冲区溢出,精心构建字符串数据可导致攻击者以mail用户的权限在系统上执行任意指令。

- 漏洞讨论

Mnews is a freely available, open source NNTP and mail client. It is designed to handle both Japanese and English character sets, and is available for the Unix and Linux operating systems.

Under some circumstances, it may be possible to exploit a buffer overflow in mnews. When a server sends a 200 response to a client, it may be possible for the server to include enough data in the response to trigger a buffer overflow. This overflow could result in the overwriting of stack memory, and the potential execution of attacker supplied instructions.
