BUGTRAQ ID: 28023 CVE(CAN) ID: CVE-2008-0595 D-BUS是一个设计目标为应用程序间通信的消息总线系统。 在评估是否应执行某一调用时，总线守护程序会查找安全策略来判断是否允许调用程序访问该调用。很多dbus服务的安全策略中包含有类似于以下的行： <allow send_interface="some.interface.WithMethods"/> 用于以白名单列出特定策略环境下用户的特定调用接口。正常情况下是以完全合格的条件调用dbus方式方式的，也就是将方式所属的接口以及方式名称都传送给了总线守护程序，但总线守护程序不要求方式调用完全合格。如果调用程序只是传送了空接口的话，总线守护程序就会试图找到相应方式的接口，并在该接口上执行调用。在这种情况下，就会忽略allow指令的send_interface属性， <allow send_interface="some.interface.WithMethods"/> 会被解释为<allow/>。这意味着如果dbus策略文件中包含有特定环境的任何<allow send_interface="..." />指令的话，就会允许该环境调用不合格的方式。 D-Bus 1.x Debian ------ Debian已经为此发布了一个安全公告（DSA-1599-1）以及相应补丁: DSA-1599-1：New dbus packages fix privilege escalation 链接：<a href=http://www.debian.org/security/2008/dsa-1599 target=_blank>http://www.debian.org/security/2008/dsa-1599</a> 补丁下载： Source archives: <a href=http://security.debian.org/pool/updates/main/d/dbus/dbus_1.0.2.orig.tar.gz...
