| Vulnerability name/brief description | Vulnerabilities in WINS Could Allow Remote Code Execution (969883) |
| CVE/CAN name | CVE-2009-1923, CVE-2009-1924 |
| Vendor threat level | Critical |
| SophosLabs threat level | Critical |
| Solution | |
| Vendor description | This security update resolves two privately reported vulnerabilities in the Windows Internet Name Service (WINS). Either vulnerability could allow remote code execution if a user received a specially crafted WINS replication packet on an affected system running the WINS service. By default, WINS is not installed on any affected operating system version. Only customers who manually install this component are affected by this issue. |
| SophosLabs comments | Although this vulnerability does not affect the majority of Windows Systems (no Windows Desktop systems are affected, and only a limited number of Windows Server systems are potentially vulnerable), because vulnerable systems can be compromised remotely and without user activity, SophosLabs considers this to be a Critical bulletin. |
| SophosLabs testing result | N/A |
| Currently known exploits | N/A |
| First sample seen | N/A |
| Discovery date | 11th August 2009 |
| Affected software | Microsoft Windows 2000 Server Service Pack 4 Windows Server 2003 Service Pack 2 Windows Server 2003 x64 Edition Service Pack 2 Windows Server 2003 with SP2 for Itanium-based Systems |
