CVE reference:CVE-2005-0047
CVE-2005-0044


Description:
Cesar Cerrudo has reported two vulnerabilities in Microsoft Windows, which can be exploited by malicious, local users to gain escalated privileges or by malicious people to compromise a vulnerable system.

1) An unspecified error in the way memory is accessed when processing COM structured storage files allows malicious, local users to execute code with escalated privileges.

2) An unchecked buffer in the process that validates OLE data can be exploited to execute arbitrary code via messages containing maliciously crafted OLE objects.

The following operating systems and software is affected by one or both of the vulnerabilities:
Microsoft Windows 2000
Microsoft Windows XP
Microsoft Windows XP 64-Bit Edition
Microsoft Windows XP 64-Bit Edition Version 2003 (Itanium)
Microsoft Windows Server 2003
Microsoft Windows Server 2003 (Itanium)
Microsoft Exchange 2000 Server
Microsoft Exchange Server 2003
Microsoft Exchange Server 5.0
Microsoft Exchange Server 5.5
Microsoft Windows 98
Microsoft Windows 98 Second Edition (SE)
Microsoft Windows Millennium Edition (ME)
Microsoft Office XP
Outlook 2002
Word 2002
