The Network News Transfer Protocol (NNTP) component of Microsoft Windows NT Server 4.0, Windows 2000 Server, Windows Server 2003, Exchange 2000 Server, and Exchange Server 2003 allows remote attackers to execute arbitrary code via XPAT patterns, possibly related to improper length validation and an "unchecked buffer," leading to off-by-one and heap-based buffer overflows.

Network Dynamic Data Exchange (NetDDE) services for Microsoft Windows 98, Windows NT 4.0, Windows 2000, Windows XP, and Windows Server 2003 allows attackers to remotely execute arbitrary code or locally gain privileges via a malicious message or application that involves an "unchecked buffer," possibly a buffer overflow.
