Microsoft » Windows 2000 : Security Vulnerabilities, CVEs, Published In 2005 CVSS score >= 6

The SynAttackProtect protection in Microsoft Windows 2003 before SP1 and Windows 2000 before SP4 with Update Roll-up uses a hash of predictable data, which allows remote attackers to cause a denial of service (CPU consumption) via a flood of SYN packets that produce identical hash values, which slows down the hash table lookups.

PNP_GetDeviceList (upnp_getdevicelist) in UPnP for Microsoft Windows 2000 SP4 and earlier, and possibly Windows XP SP1 and earlier, allows remote attackers to cause a denial of service (memory consumption) via a DCE RPC request that specifies a large output buffer size, a variant of CVE-2006-6296, and a different vulnerability than CVE-2005-2120.

Microsoft Windows 2000 before Update Rollup 1 for SP4 does not record the IP address of a Windows Terminal Services client in a security log event if the client connects successfully, which could make it easier for attackers to escape detection.

Microsoft Windows 2000 before Update Rollup 1 for SP4 allows a local administrator to unlock a computer even if it has been locked by a domain administrator, which allows the local administrator to access the session as the domain administrator.

The SECEDIT command on Microsoft Windows 2000 before Update Rollup 1 for SP4, when using a security template to set Access Control Lists (ACLs) on folders, does not apply ACLs on folders that are listed after a long folder entry, which could result in less secure permissions than specified by the template.

The thread termination routine in the kernel for Windows NT 4.0 and 2000 (NTOSKRNL.EXE) allows local users to modify kernel memory and execution flow via steps in which a terminating thread causes Asynchronous Procedure Call (APC) entries to free the wrong data, aka the "Windows Kernel Vulnerability."

Buffer overflow in a certain USB driver, as used on Microsoft Windows, allows attackers to execute arbitrary code.

Unspecified vulnerability in the Graphics Rendering Engine (GDI32.DLL) in Windows 2000 SP4, XP SP1 and SP2, and Server 2003 SP1, related to "An unchecked buffer" and possibly buffer overflows, allows remote attackers to execute arbitrary code via a crafted Windows Metafile (WMF) format image, aka "Windows Metafile Vulnerability."

Multiple integer overflows in the Graphics Rendering Engine (GDI32.DLL) in Windows 2000 SP4, XP SP1 and SP2, and Server 2003 SP1 allow remote attackers to execute arbitrary code via crafted Windows Metafile (WMF) and Enhanced Metafile (EMF) format images that lead to heap-based buffer overflows, as demonstrated using MRBP16::bCheckRecord.

Windows Shell for Microsoft Windows 2000 SP4, XP SP1 and SP2, and Server 2003 allows remote attackers to execute arbitrary commands via a shortcut (.lnk) file with long font properties that lead to a buffer overflow in the Client/Server Runtime Server Subsystem (CSRSS), a different vulnerability than CVE-2005-2118.

Stack-based buffer overflow in the Plug and Play (PnP) service (UMPNPMGR.DLL) in Microsoft Windows 2000 SP4, and XP SP1 and SP2, allows remote or local authenticated attackers to execute arbitrary code via a large number of "\" (backslash) characters in a registry key name, which triggers the overflow in a wsprintfW function call.

Buffer overflow in Collaboration Data Objects (CDO), as used in Microsoft Windows and Microsoft Exchange Server, allows remote attackers to execute arbitrary code when CDOSYS or CDOEX processes an e-mail message with a large header name, as demonstrated using the "Content-Type" string.

The Client Service for NetWare (CSNW) on Microsoft Windows 2000 SP4, XP SP1 and Sp2, and Server 2003 SP1 and earlier, allows remote attackers to execute arbitrary code due to an "unchecked buffer" when processing certain crafted network messages.

Buffer overflow in the Print Spooler service (Spoolsv.exe) for Microsoft Windows 2000, Windows XP, and Windows Server 2003 allows remote attackers to execute arbitrary code via a malicious message.

Stack-based buffer overflow in the Plug and Play (PnP) service for Microsoft Windows 2000 and Windows XP Service Pack 1 allows remote attackers to execute arbitrary code via a crafted packet, and local users to gain privileges via a malicious application, as exploited by the Zotob (aka Mytob) worm.

COM+ in Microsoft Windows does not properly "create and use memory structures," which allows local users or remote attackers to execute arbitrary code.

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.

Buffer overflow in Microsoft Step-by-Step Interactive Training (orun32.exe) allows remote attackers to execute arbitrary code via a bookmark link file (.cbo, cbl, or .cbm extension) with a long User field.

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.

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."

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.

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.

The Windows Animated Cursor (ANI) capability in Windows NT, Windows 2000 through SP4, Windows XP through SP1, and Windows 2003 allows remote attackers to execute arbitrary code via the AnimationHeaderBlock length field, which leads to a stack-based buffer overflow.

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.
