Description
Object linking and embedding (OLE) Automation, as used in Microsoft Windows 2000 SP4, XP SP2, Server 2003 SP1 and SP2, Office 2004 for Mac, and Visual Basic 6.0 allows remote attackers to execute arbitrary code via the substringData method on a TextNode object, which causes an integer overflow that leads to a buffer overflow.
