netman.dll in Microsoft Windows Connections Manager Library allows local users to cause a denial of service (Network Connections Service crash) via a large integer argument to a particular function, aka "Network Connection Manager Vulnerability."Show less

Windows NT 4.0 and Windows 2000 before URP1 for Windows 2000 SP4 does not properly prevent NULL sessions from accessing certain alternate named pipes, which allows remote attackers to (1) list Windows services via svcctl or (2) read eventlogs via eventlog.Show less

Integer overflow in Microsoft Windows 98, 2000, XP SP2 and earlier, and Server 2003 SP1 and earlier allows remote attackers to execute arbitrary code via a crafted compiled Help (.CHM) file with a large size field that triggers a heap-based buffer overflow, as demonstrated using a "ms-its:" URL in Internet Explorer.Show less

Buffer overflow in the Server Message Block (SMB) functionality for Microsoft Windows 2000, XP SP1 and SP2, and Server 2003 and SP1 allows remote attackers to execute arbitrary code via unknown vectors, aka the "Server Message Block Vulnerability."Show less

Heap-based buffer overflow in the BERDecBitString function in Microsoft ASN.1 library (MSASN1.DLL) allows remote attackers to execute arbitrary code via nested constructed bit strings, which leads to a realloc of a non-null pointer and causes the function to overwrite previously freed memory, as demonstrated using a SPNEGO token with a constructed bit string during HTTP authentication, and a different vulnerability than CVE-2003-0818. NOTE: the researcher has claimed that MS:MS04-007 fixes this issue.Show less

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.Show less

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.Show less

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.Show less

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."Show less

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.Show less

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".Show less

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.Show less

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.Show less

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.Show less
