Black Ice多个ActiveX控件栈溢出及内存破坏漏洞
Black Ice多个ActiveX控件栈溢出及内存破坏漏洞--------------------------------------------------------------------------------
受影响系统：
Black Ice Barcode SDK 5.01
描述：
--------------------------------------------------------------------------------
BUGTRAQ ID: 29579
Black Ice Barcode SDK工具包提供各种1D和2D条码功能函数库。
Black Ice Barcode SDK所提供的多个ActiveX控件中存在安全漏洞，如果用户受骗访问了恶意网页的话，就可能导致执行任意代码或向系统中的任意位置写入文件。
1) BIDIB.BIDIBCtrl.1 ActiveX控件（BIDIB.ocx）没有安全的调用DownloadImageFileURL()方式，可能导致向系统的任意位置下载任意文件，或通过超长参数触发内存破坏。
2) BITIFF.BITiffCtrl.1 ActiveX控件（BITiff.ocx）在处理SetByteOrder()方式时存在栈溢出漏洞，可能导致执行任意指令。
