漏洞描述
中文描述:
Exim[1]是一款流行的EMAIL服务器(MTA)。 Exim没有正确处理畸形EHLO/HELO消息，远程攻击者可以利用这个漏洞对Exim服务器进行基于堆的破坏，可导致拒绝服务攻击。 问题存在于exim-4.20/src/smtp_in.c中： if (*smtp_data == 0) Ustrcpy(smtp_data， "(no argument given)"); 'smtp_data'是指向513字节的'cmd_buffer'堆缓冲区。精心构建HELO或者EHLO命令可以使'*smtp_data'为零及'smtp_data'包含在'cmd_buffer'中最后的2个字节中，因此字符串"o argument given)"后面的NULL会溢出cmd_buffer缓冲区。由于固定字符串覆盖缓冲区并受到一定条件的限制，根据作者报告此漏洞目前看来难于利用。一般攻击者可对服务器进行拒绝服务攻击。
英文描述:
Heap-based buffer overflow in smtp_in.c for Exim 3 (exim3) before 3.36 and Exim 4 (exim4) before 4.21 may allow remote attackers to execute arbitrary code via an invalid (1) HELO or (2) EHLO argument with a large number of spaces followed by a NULL character and a newline, which is not properly trimmed before the "(no argument given)" string is appended to the buffer.
