OpenAFS for Microsoft Windows本地拒绝服务漏洞

OpenAFS是一套开放源代码的分布式文件系统。 Windows平台下的OpenAFS存在设计错误，本地攻击者可以利用漏洞对系统进行拒绝服务攻击。 Windows平台下的OpenAFS安装一个网络提供模块afslogon.dll，此模块由Windows Logon服务装载，当MIT Kerberos For windows安装时，afslogon.dll会尝试对Kerberos v5库执行操作。成功使用Kerberos v5库需要有能力建立一个krb5_context。在Kerberos v5配置文件krb5.ini中的解析错误，可阻止krb5_context成功建立。无论是否成功建立，afslogon.dll尝试释放krb5_context，这可导致内存访问错误而Windows Logon服务终止，使系统停止响应。 OpenAFS OpenAFS 1.5.18
