Cistron RADIUS远程有符号NAS-PORT值导致内存破坏漏洞
Vulnerability Description
radiusd-cistron是一款RADIUS协议实现。 Cistron-RADIUS服务器没有正确处理超大NAS号，远程攻击者可以利用这个漏洞破坏服务进程内存信息，可能以进程权限在系统上执行任意指令。 Cistron RADIUS当处理用户提供的数据时在调用sprintf()函数时没有正确使用"%d"格式符，攻击者如果传送一个有符号值作为NAS-Port端口数据，就可以导致覆盖服务器进程的内部内存数据，精心构建提交数据可能以RADIUS进程权限(一般是root)在系统上执行任意指令。 有漏洞代码如下：
