CVE-2004-0574
HighSummary
The NNTP component in Microsoft Windows NT Server 4.0, Windows 2000 Server, Windows Server 2003, Exchange 2000 Server, and Exchange Server 2003 contains a vulnerability that allows remote code execution via specially crafted XPAT patterns. The issue is due to improper length validation and heap-based buffer overflows (off-by-one and heap-based buffer overflow).
Risk Assessment
An attacker can remotely execute arbitrary code on the vulnerable server, potentially leading to full system compromise, data theft, or service disruption.
Recommendation
Apply the security update provided by Microsoft in bulletin MS04-036 immediately. If patching is not possible, consider disabling the NNTP service or restricting access to trusted IP addresses.

Original NVD description (English source)
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.
