Microsoft » Windows 2000 : Security Vulnerabilities, CVEs, Published In May 2005

The Web View DLL (webvw.dll), as used in Windows Explorer on Windows 2000 systems, does not properly filter an apostrophe ("'") in the author name in a document, which allows attackers to execute arbitrary script via extra attributes when Web View constructs a mailto: link for the preview pane when the user selects the file.

The TCP/IP stack in multiple operating systems allows remote attackers to cause a denial of service (CPU consumption) via a TCP packet with the correct sequence number but the wrong Acknowledgement number, which generates a large number of "keep alive" packets. NOTE: some followups indicate that this issue could not be replicated.

The GetEnhMetaFilePaletteEntries API in GDI32.DLL in Windows 2000 allows remote attackers to cause a denial of service (application crash) via a crafted Enhanced Metafile (EMF) file that causes invalid (1) end, (2) emreof, or (3) palent offsets to be used, aka "Enhanced Metafile Vulnerability."

Stack-based buffer overflow in WINSRV.DLL in the Client Server Runtime System (CSRSS) process of Microsoft Windows 2000, Windows XP SP1 and SP2, and Windows Server 2003 allows local users to gain privileges via a specially-designed application that provides console window information with a long FaceName value.

Buffer overflow in Microsoft Windows 2000, Windows XP SP1 and SP2, and Windows Server 2003 allows local users to cause a denial of service (i.e., system crash) via a malformed request, aka "Object Management Vulnerability".

Microsoft Windows XP Pro SP2 and Windows 2000 Server SP4 running Active Directory allow local users to bypass group policies that restrict access to hidden drives by using the browse feature in Office 10 applications such as Word or Excel, or using a flash drive. NOTE: this issue has been disputed in a followup post.

Multiple TCP implementations with Protection Against Wrapped Sequence Numbers (PAWS) with the timestamps option enabled allow remote attackers to cause a denial of service (connection loss) via a spoofed packet with a large timer value, which causes the host to discard later packets because they appear to be too old.

The document processing application used by the Windows Shell in Microsoft Windows 2000, Windows XP, and Windows Server 2003 allows remote attackers to execute arbitrary code by modifying the CLSID stored in a file so that it is processed by HTML Application Host (MSHTA), as demonstrated using a Microsoft Word document.

The kernel of Microsoft Windows 2000, Windows XP SP1 and SP2, and Windows Server 2003 allows local users to gain privileges via certain access requests.

Buffer overflow in the font processing component of Microsoft Windows 2000, Windows XP SP1 and SP2, and Windows Server 2003 allows local users to gain privileges via a specially-designed application.

Buffer overflow in the Message Queuing component of Microsoft Windows 2000 and Windows XP SP1 allows remote attackers to execute arbitrary code via a crafted message.

The Hyperlink Object Library for Windows 98, 2000, XP, and Server 2003 allows remote attackers to execute arbitrary code via a crafted link that triggers an "unchecked buffer" in the library, possibly due to a buffer overflow.

Internet Explorer 5.01, 5.5, and 6 allows remote attackers to execute arbitrary code via drag and drop events, aka the "Drag-and-Drop Vulnerability."

The License Logging service for Windows NT Server, Windows 2000 Server, and Windows Server 2003 does not properly validate the length of messages, which leads to an "unchecked buffer" and allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code, aka the "License Logging Service Vulnerability."

Microsoft Windows XP SP2 and earlier, 2000 SP3 and SP4, Server 2003, and older operating systems allows remote attackers to cause a denial of service and possibly execute arbitrary code via crafted IP packets with malformed options, aka the "IP Validation Vulnerability."

Windows 2000, XP, and Server 2003 does not properly "validate the use of memory regions" for COM structured storage files, which allows attackers to execute arbitrary code, aka the "COM Structured Storage Vulnerability."

The Server Message Block (SMB) implementation for Windows NT 4.0, 2000, XP, and Server 2003 does not properly validate certain SMB packets, which allows remote attackers to execute arbitrary code via Transaction responses containing (1) Trans or (2) Trans2 commands, aka the "Server Message Block Vulnerability," and as demonstrated using Trans2 FIND_FIRST2 responses with large file name length fields.

The OLE component in Windows 98, 2000, XP, and Server 2003, and Exchange Server 5.0 through 2003, does not properly validate the lengths of messages for certain OLE data, which allows remote attackers to execute arbitrary code, aka the "Input Validation Vulnerability."
