Microsoft OLE Remote Buffer Overflow Vulnerability

Microsoft OLE Remote Buffer Overflow Vulnerability

Microsoft OLE is reported prone to a remote buffer overflow vulnerability. This issue arises because the application fails to perform boundary checks before copying user-supplied data to sensitive process buffers. A remote attacker may leverage this vulnerability to execute arbitrary code on a vulnerable computer.

If a vulnerable user opens a malicious file through any application that supports OLE, the attacker-supplied arbitrary code may be executed in the context of the user.

Reportedly, user interaction is required to exploit this condition in Microsoft Windows 2000, Windows XP, and Windows Server 2003.

An anonymous remote user can exploit this issue in various versions of Microsoft Exchange Server because Exchange Server uses the affected Windows OLE component. A successful attack can allow the attacker to gain SYSTEM privileges as the Microsoft Exchange Server runs with elevated privileges. Affected Microsoft Exchange Server versions include Microsoft Exchange 2000 Server, Microsoft Exchange Server 2003, Microsoft Exchange Server 5.0, and Microsoft Exchange Server 5.5.

Other applications that use the affected Windows OLE component include Microsoft Office XP Service Pack 3, Microsoft Office XP Service Pack 2, Microsoft Office 2003 Service Pack 1, and Microsoft Office 2003.
