CVE-2004-2339: Microsoft Windows 2000

High severity, CVSS 8.4. EPSS: 1.4% chance of exploitation in the next 30 days.

Microsoft Windows 2000, XP, and possibly 2003 allows local users with the SeDebugPrivilege privilege to execute arbitrary code as kernel and read or write kernel memory via the NtSystemDebugControl function, which does not verify its pointer arguments. Note: this issue has been disputed, since Administrator privileges are typically required to exploit this issue, thus privilege boundaries are not crossed

Affected products

• Microsoft Windows 2000: any version
• Microsoft Windows 2003 Server: version r2 only
• Microsoft Windows XP: any version
