BUGTRAQ  ID: 36698
CVE ID: CVE-2009-3031

Symantec Altiris Deployment Solution是自动化的操作系统部署解决方案,用于从统一的位置部署和管理服务器、桌面和笔记本等。

在初次连接到Altiris Deployment Solution等产品管理服务器的Web控制台时会安装一个AeXNSConsoleUtilities.dll ActiveX控件以授权到服务器的管理员访问,而该控件的BrowseAndSaveFile函数存在栈溢出漏洞。如果用户受骗访问了恶意网页并向该函数传送了超长参数的话,就可以触发这个溢出,导致执行任意指令。
