Apache1.2.5版本及之前版本存在缓冲区溢出漏洞。远程攻击者导致带有大量包含/字符的GET请求的服务拒绝。

source: http://www.securityfocus.com/bid/2216/info

Apache Web Server 1.2 and previous versions are subject to a denial of service. By requesting a malformed GET request composed of an unusually large number of '/' characters, an attacker can cause CPU usage to spike. A restart of the service is required to gain normal functionality.
