Microsoft : Security Vulnerabilities, CVEs, Published In 1999 (Denial of service) CVSS score >= 2

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

Buffer overflow in FTP server in Microsoft IIS 3.0 and 4.0 allows local and sometimes remote attackers to cause a denial of service via a long NLST (ls) command.

IIS 3.x and 4.x does not distinguish between pages requiring encryption and those that do not, which allows remote attackers to cause a denial of service (resource exhaustion) via SSL requests to the HTTPS port for normally unencrypted files, which will cause IIS to perform extra work to send the files over SSL.

The Sun HotSpot Performance Engine VM allows a remote attacker to cause a denial of service on any server running HotSpot via a URL that includes the [ character.

Windows NT 4.0 allows local users to cause a denial of service (crash) via an illegal kernel mode address to the functions (1) GetThreadContext or (2) SetThreadContext.

Windows NT 3.51 and 4.0 allow local users to cause a denial of service (crash) by running a program that creates a large number of locks on a file, which exhausts the NonPagedPool.

Win32k.sys in Windows NT 4.0 before SP2 allows local users to cause a denial of service (crash) by calling certain WIN32K functions with incorrect parameters.

Windows NT 4.0 allows local users to cause a denial of service via a user mode application that closes a handle that was opened in kernel mode, which causes a crash when the kernel attempts to close the handle.

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.

LSA (LSASS.EXE) in Windows NT 4.0 allows remote attackers to cause a denial of service via a NULL policy handle in a call to (1) SamrOpenDomain, (2) SamrEnumDomainUsers, and (3) SamrQueryDomainInfo.

IIS 3.0 allows remote attackers to cause a denial of service via a request to an ASP page in which the URL contains a large number of / (forward slash) characters.

Netbt.sys in Windows NT 4.0 allows remote malicious DNS servers to cause a denial of service (crash) by returning 0.0.0.0 as the IP address for a DNS host name lookup.

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.

Microsoft Outlook client allows remote attackers to cause a denial of service by sending multiple email messages with the same X-UIDL headers, which causes Outlook to hang.

Tcpip.sys in Windows NT 4.0 before SP4 allows remote attackers to cause a denial of service via an ICMP Subnet Mask Address Request packet, when certain multiple IP addresses are bound to the same network interface.

FTP service in IIS 4.0 and earlier allows remote attackers to cause a denial of service (resource exhaustion) via many passive (PASV) connections at the same time.

Windows NT 4.0 allows remote attackers to cause a denial of service (crash) via extra source routing data such as (1) a Routing Information Field (RIF) field with a hop count greater than 7, or (2) a list containing duplicate Token Ring IDs.

Windows NT 4.0 does not properly shut down invalid named pipe RPC connections, which allows remote attackers to cause a denial of service (resource exhaustion) via a series of connections containing malformed data, aka the "Named Pipes Over RPC" vulnerability.

Microsoft Exchange Server 5.5 and 5.0 does not properly handle (1) malformed NNTP data, or (2) malformed SMTP data, which allows remote attackers to cause a denial of service (application error).

IIS 3.0 and 4.0 on x86 and Alpha allows remote attackers to cause a denial of service (hang) via a malformed GET request, aka the IIS "GET" vulnerability.

Microsoft HTML control as used in (1) Internet Explorer 5.0, (2) FrontPage Express, (3) Outlook Express 5, and (4) Eudora, and possibly others, allows remote malicious web site or HTML emails to cause a denial of service (100% CPU consumption) via large HTML form fields such as text inputs in a table cell.

Microsoft SQL 7.0 server allows a remote attacker to cause a denial of service via a malformed TDS packet.

Windows NT Local Security Authority (LSA) allows remote attackers to cause a denial of service via malformed arguments to the LsaLookupSids function which looks up the SID, aka "Malformed Security Identifier Request."

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

Buffer overflows in Windows NT 4.0 print spooler allow remote attackers to gain privileges or cause a denial of service via a malformed spooler request.
