Buffer overflow in the TCP/IP Protocol driver in Microsoft Windows 2000 SP4, XP SP1 and SP2, and Server 2003 SP1 and earlier allows remote attackers to execute arbitrary code via unknown vectors related to IP source routing.

Buffer overflow in the plug-in for Microsoft Windows Media Player (WMP) 9 and 10, when used in browsers other than Internet Explorer and set as the default application to handle media files, allows remote attackers to execute arbitrary code via HTML with an EMBED element containing a long src attribute.

Heap-based buffer overflow in T2EMBED.DLL in Microsoft Windows 2000 SP4, XP SP1 and SP2, and Server 2003 up to SP1, Windows 98, and Windows ME allows remote attackers to execute arbitrary code via an e-mail message or web page with a crafted Embedded Open Type (EOT) web font that triggers the overflow during decompression.

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 Local Procedure Call (LPC) interface of the Windows Kernel for Windows NT 4.0, Windows 2000, Windows XP, and Windows Server 2003 does not properly validate the lengths of messages sent to the LPC port, which allows local users to gain privileges, aka "Windows Kernel Vulnerability."

HyperTerminal application for Windows NT 4.0, Windows 2000, Windows XP, and Windows Server 2003 does not properly validate the length of a value that is saved in a session file, which allows remote attackers to execute arbitrary code via a malicious HyperTerminal session file (.ht), web site, or Telnet URL contained in an e-mail message, triggering a buffer overflow.

Heap-based buffer overflow in winhlp32.exe in Windows NT, Windows 2000 through SP4, Windows XP through SP2, and Windows 2003 allows remote attackers to execute arbitrary code via a crafted .hlp file.
