Integer overflow in DUNZIP32.DLL for Microsoft Windows XP, Windows XP 64-bit Edition, Windows Server 2003, and Windows Server 2003 64-bit Edition allows remote attackers to execute arbitrary code via compressed (zipped) folders that involve an "unchecked buffer" and improper length validation.

Integer overflow in Microsoft Windows 98, 2000, XP SP2 and earlier, and Server 2003 SP1 and earlier allows remote attackers to execute arbitrary code via a crafted compiled Help (.CHM) file with a large size field that triggers a heap-based buffer overflow, as demonstrated using a "ms-its:" URL in Internet Explorer.

Buffer overflow in the Winsock API in Microsoft Windows 2000 SP4, XP SP1 and SP2, and Server 2003 SP1 allows remote attackers to execute arbitrary code via unknown vectors, aka "Winsock Hostname Vulnerability."

Buffer overflow in the Server Service in Microsoft Windows 2000 SP4, XP SP1 and SP2, and Server 2003 SP1 allows remote attackers, including anonymous users, to execute arbitrary code via a crafted RPC message, a different vulnerability than CVE-2006-1314.

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.

The HTML Help ActiveX control (Hhctrl.ocx) in Microsoft Windows 2000 SP3, XP SP2 and Professional, 2003 SP1 allows remote attackers to execute arbitrary code via unspecified functions, related to uninitialized parameters.
