A multi-threaded race condition in the Windows RPC DCOM functionality with the MS03-039 patch installed allows remote attackers to cause a denial of service (crash or reboot) by causing two threads to process the same RPC request, which causes one thread to use memory after it has been freed, a different vulnerability than CVE-2003-0352 (Blaster/Nachi), CVE-2003-0715, and CVE-2003-0528, and as demonstrated by certain exploits against those vulnerabilities.

Buffer overflow in the HTML Converter (HTML32.cnv) on various Windows operating systems allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via cut-and-paste operation, as demonstrated in Internet Explorer 5.0 using a long "align" argument in an HR tag.

Integer overflow in JsArrayFunctionHeapSort function used by Windows Script Engine for JScript (JScript.dll) on various Windows operating system allows remote attackers to execute arbitrary code via a malicious web page or HTML e-mail that uses a large array index value that enables a heap-based buffer overflow attack.

The Internet Group Management Protocol (IGMP) allows local users to cause a denial of service via an IGMP membership report to a target's Ethernet address instead of the Multicast group address, which causes the target to stop sending reports to the router and effectively disconnect the group from the network.

The default configuration for the domain name resolver for Microsoft Windows 98, NT 4.0, 2000, and XP sets the QueryIpMatching parameter to 0, which causes Windows to accept DNS updates from hosts that it did not query, which allows remote attackers to poison the DNS cache.

The CIFS Computer Browser service allows remote attackers to cause a denial of service by sending a ResetBrowser frame to the Master Browser, aka the "ResetBrowser Frame" vulnerability.

Windows 95 and Windows 98 allow a remote attacker to cause a denial of service via a NetBIOS session request packet with a NULL source name.

The networking software in Windows 95 and Windows 98 allows remote attackers to execute commands via a long file name string, aka the "File Access URL" vulnerability.

Windows 95, Windows 98, Windows 2000, Windows NT 4.0, and Terminal Server systems allow a remote attacker to cause a denial of service by sending a large number of identical fragmented IP packets, aka jolt2 or the "IP Fragment Reassembly" vulnerability.

Microsoft Windows 9x operating systems allow an attacker to cause a denial of service via a pathname that includes file device names, aka the "DOS Device in Path Name" vulnerability.

Windows NT Autorun executes the autorun.inf file on non-removable media, which allows local attackers to specify an alternate program to execute when other users access a drive.

Buffer overflow in the SHGetPathFromIDList function of the Serv-U FTP server allows attackers to cause a denial of service by performing a LIST command on a malformed .lnk file.

Buffer overflow in Microsoft Rich Text Format (RTF) reader allows attackers to cause a denial of service via a malformed control word.

Windows 95, 98, and NT 4.0 allow remote attackers to cause a denial of service by spoofing ICMP redirect messages from a router, which causes Windows to change its routing tables.

Windows 95 and Windows 98 systems, when configured with multiple TCP/IP stacks bound to the same MAC address, allow remote attackers to cause a denial of service (traffic amplification) via a certain ICMP echo (ping) packet, which causes all stacks to send a ping response, aka TCP Chorusing.

The Windows help system can allow a local user to execute commands as another user by editing a table of contents metafile with a .CNT extension and modifying the topic action to include the commands to be executed when the .hlp file is accessed.

Denial of service in various Windows systems via malformed, fragmented IGMP packets.

Buffer overflow in Microsoft Telnet client in Windows 95 and Windows 98 via a malformed Telnet argument.

A remote attacker can disable the virus warning mechanism in Microsoft Excel 97.

A system does not present an appropriate legal message or warning to a user who is accessing it.

Remote attackers can perform a denial of service in Windows machines using malicious ARP packets, forcing a message box display for each packet or filling up log files.

A legacy credential caching mechanism used in Windows 95 and Windows 98 systems allows attackers to read plaintext network passwords.

Windows 98 and other operating systems allows remote attackers to cause a denial of service via crafted "oshare" packets, possibly involving invalid fragmentation offsets.

Buffer overflow in Quintessential Player 4.50.1.82 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted (1) M3u or (2) M3u-8 file; or a (3) crafted PLS file with a long value in the (a) NumberofEntries, (b) Length (aka Length1), (c) Filename (aka File1), (d) Title (aka Title1) field, or other unspecified fields.

TCP, when using a large Window Size, makes it easier for remote attackers to guess sequence numbers and cause a denial of service (connection loss) to persistent TCP connections by repeatedly injecting a TCP RST packet, especially in protocols that use long-lived connections, such as BGP.

Microsoft Internet Explorer 6.0.2900 SP2 and earlier allows remote attackers to cause a denial of service (crash) via a table element with a CSS attribute that sets the position, which triggers an "unhandled exception" in mshtml.dll.

User32.DLL in Microsoft Windows 98SE, and possibly other operating systems, allows local and remote attackers to cause a denial of service (crash) via an icon (.ico) bitmap file with large width and height values.

Interactions between the CIFS Browser Protocol and NetBIOS as implemented in Microsoft Windows 95, 98, NT, and 2000 allow remote attackers to modify dynamic NetBIOS name cache entries via a spoofed Browse Frame Request in a unicast or UDP broadcast datagram.

NETBIOS client in Windows 95 and Windows 98 allows a remote attacker to cause a denial of service by changing a file sharing service to return an unknown driver type, which causes the client to crash.

Various TCP/IP stacks and network applications allow remote attackers to cause a denial of service by flooding a target host with TCP connection attempts and completing the TCP/IP handshake without maintaining the connection state on the attacker host, aka the "NAPTHA" class of vulnerabilities. NOTE: this candidate may change significantly as the security community discusses the technical nature of NAPTHA and learns more about the affected applications. This candidate is at a higher level of abstraction than is typical for CVE.
