Vulnerability Title
MIT Kerberos KDC 'do_as_req.c'双重释放内存破坏漏洞
Vulnerability Description
Kerberos是一款广泛使用的超强加密来验证客户端和服务器端的网络协议。 MIT Kerberos在"do_as_req.c"的实现上存在远程内存破坏漏洞，攻击者可利用此漏洞以超级用户的权限，借助包含类型化数据的e_data字段，执行任意代码，完全控制受影响计算机，造成拒绝服务。 如果krb5-1.7或较高版本的KDC配置为响应PKINIT请求，即启用了"初始验证公开密钥加密"PKINIT功能，就会受到双重释放内存破坏漏洞的影响，造成程序崩溃或执行任意代码。
