漏洞描述
中文描述:

mod_proxy是一个可在Apache使用的代理模块。mod_proxy在处理负的Content-Length值时存在问题，远程攻击者可以利用这个漏洞进行缓冲区溢出攻击，可能以Apache进程权限在系统上执行任意指令。连接远程服务器使其返回非法(负值)的Content-Length，可使Mod_proxy触发基于整数的溢出，会导致Apache子进程崩溃。问题存在于proxy_util.c中：n = ap_bread(f， buf， MIN((int)buf_size，(int)(len - total_bytes_rcvd)));这里len可为负值。 在旧的OpenBSD/FreeBSD系统中可利用memcpy的反向拷贝实现来执行任意指令。新的BSD系统中由于攻击者可以控制3个任意字节也能用于执行任意指令。如果define AP_ENABLE_EXCEPTION_HOOK启用的情况下，可能在任何平台都可被利用。

英文描述:

Heap-based buffer overflow in proxy_util.c for mod_proxy in Apache 1.3.25 to 1.3.31 allows remote attackers to cause a denial of service (process crash) and possibly execute arbitrary code via a negative Content-Length HTTP header field, which causes a large amount of data to be copied.
