**Name of the Vulnerable Software and Affected Versions** Microsoft Windows Server 2003 SP2 **Description** The issue is caused by the Windows TCP/IP stack failing to properly handle objects in memory during IOCTL processing, allowing an attacker to run arbitrary code in the context of another process. If the process runs with administrator privileges, an attacker could install programs, view, change, or delete data, or create new accounts with full user rights. **Recommendations** For Microsoft Windows Server 2003 SP2, at the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Microsoft Windows XP versions SP2 through SP3 Microsoft Windows Server 2003 version SP2 **Description** The issue exists in the NDProxy component of the Windows kernel due to improper validation of input passed from user mode to the kernel. This allows an attacker to run code in kernel mode, potentially giving them complete control over the system. The attacker could then install programs, view, change, or delete data, or create new accounts with full administrator rights. The vulnerability has been exploited in the wild. **Recommendations** For Microsoft Windows XP versions SP2 through SP3, consider applying security updates to address the issue. For Microsoft Windows Server 2003 version SP2, apply the relevant security patch to mitigate the risk of exploitation. As a temporary workaround, consider restricting access to the NDProxy component until a patch is applied.

**Name of the Vulnerable Software and Affected Versions** Microsoft Windows XP versions SP2 through SP3 Microsoft Windows Server 2003 version SP2 Microsoft Windows Vista versions SP1 through SP2 Microsoft Windows Server 2008 versions Gold through R2 SP1 Microsoft Windows 7 versions Gold through SP1 **Description** The issue arises from the improper validation of user-mode input by the Ancillary Function Driver (AFD) in afd.sys, allowing local users to gain privileges via a crafted application. This could enable an attacker to run code with elevated privileges, potentially leading to the execution of arbitrary code and complete control of an affected system. The attacker could then install programs, view, change, or delete data, or create new accounts with full user rights. **Recommendations** For Microsoft Windows XP versions SP2 through SP3, update to a newer version that includes the fix for this issue. For Microsoft Windows Server 2003 version SP2, update to a newer version that includes the fix for this issue. For Microsoft Windows Vista versions SP1 through SP2, update to a newer version that includes the fix for this issue. For Microsoft Windows Server 2008 versions Gold through R2 SP1, update to a newer version that includes the fix for this issue. For Microsoft Windows 7 versions Gold through SP1, update to a newer version that includes the fix for this issue.
