CVE-2006-3441

High
Published: Translated: NVD NIST

Summary

A buffer overflow in the DNS Client service of Microsoft Windows 2000 SP4, XP SP1/SP2, and Server 2003 SP1 allows remote attackers to execute arbitrary code via a crafted DNS server response. Multiple vectors exist, including a heap-based buffer overflow in a DNS server response, malformed ATMA records, and a length miscalculation in TXT, HINFO, X25, and ISDN records.

Risk Assessment

The vulnerability enables unauthenticated remote code execution, potentially leading to full system compromise. Organizations using the affected Windows versions are at risk of network-based attacks.

Recommendation

Immediately apply security update MS06-041 or a later Windows update. If patching is not possible, consider disabling the DNS Client service or restricting DNS traffic to trusted servers.

Buffer overflow in the DNS Client service in Microsoft Windows 2000 SP4, XP SP1 and SP2, and Server 2003 SP1 allows remote attackers to execute arbitrary code via a crafted record response. NOTE: while MS06-041 implies that there is a single issue, there are multiple vectors, and likely multiple vulnerabilities, related to (1) a heap-based buffer overflow in a DNS server response to the client, (2) a DNS server response with malformed ATMA records, and (3) a length miscalculation in TXT, HINFO, X25, and ISDN records.
