ZDnet의 한 블로그에서는 4월 달에 문제가 되었던 ANI 관련 취약점에 대한 일부 숨겨진 사실을 공개했습니다. 한 보안 연구기관에서는 이미 작년 12월 말 경에 이러한 취약점이 있음을 마이크로소프트에 알렸지만, 3월까지 어떤 패치도 제공되지 않았다고 주장했습니다.

2007년에는 3월까지 모두 16개의 취약점이 발표되었으며, 패치도 함께 공개되었습니다 하지만, ANI 관련 취약점은 이러한 중대한 결함에도 불구하고, 패치를 하지 않은 상태로 놔뒀습니다.

이러한 두 단체간의 진실 공방이 진행되는 그러한 게시물입니다. 자세한 내용은 아래 원문을 참고하세요.

    지난 3월 말에 ANI 관련 보안 취약점이 공개되었습니다. 어제인 4월 4일 오전에 긴급 패치가 제공되어 일단은 진정 국면으로 돌아선 상태입니다. 이 보안 패치는 불법 복제 제품에서도 다운로드가 가능합니다.

    아래 글은 PC WELT라는 잡지에서 바이러스 백신 제작사들이 얼마나 빠른 대응 속도로 ANI 익스플로잇을 검출해 내는지 조사한 기사입니다. 참고로, ANI 익스플로잇은 최초에 중국에서 3개의 샘플이 나오기 시작하였고, 그 이후 소스의 분석을 통해 기하급수적으로 증가했습니다.

    MS의 정식 패치가 나오기 전이었기 때문에 대부분의 경우, 노가다(?) 작업이 이루어졌을 것이라는 짐작이 가능합니다. 즉, 새로운 변종이 나오면 재빨리 데이터베이스에 업그레이드했을 것입니다. 일부 휴리스틱 진단을 하는 백신의 경우 좀더 나의 진단율을 보인 것도 이때문으로 보입니다.

    AV-Test(http://av-test.org)에서는 ANI 익스플로잇의 변종 가운데 가장 위험한 144개의 샘플을 입수하여 전세계에서 가장 많이 판매되고 있는 30가지 바이러스 백신으로 검사하여 진단율을 조사하였습니다.

    가장 높은 진단율을 보인 제품은 "Web which ago"이고, F-Secure가 그 뒤를 바짝 따르고 있습니다. 참고로, Bitdefender는 검사에서 약간 낮은 진단율을 보여 줬는데, 그 이유는 테스트 시점에 공식 업데이트를 제공하지 않았기 때문입니다.

      지난 3월 30일경 발표되었던 ANI 관련 취약점에 대한 보안 패치가 4월 3일(미국)에 발표되었습니다. 이 패치는 지난번에 가장 급박하게 진행되었던 WMF 관련 취약점에 이어 발생한 두 번째 ANI 관련 취약점을 해결해 줍니다.

      Office Update 

      Software Update Services:

      By using Microsoft Software Update Services (SUS), administrators can quickly and reliably deploy the latest critical updates and security updates to Windows 2000 and Windows Server 2003-based servers, and to desktop systems that are running Windows 2000 Professional or Windows XP Professional.

      For more information about how to deploy security updates by using Software Update Services, visit the Software Update Services Web site.

      Windows Server Update Services:

      By using Windows Server Update Services (WSUS), administrators can quickly and reliably deploy the latest critical updates and security updates for Windows 2000 operating systems and later, Office XP and later, Exchange Server 2003, and SQL Server 2000 onto Windows 2000 and later operating systems.

      For more information about how to deploy security updates using Windows Server Update Services, visit the Windows Server Update Services Web site.

      Systems Management Server:

      Microsoft Systems Management Server (SMS) delivers a highly configurable enterprise solution for managing updates. By using SMS, administrators can identify Windows-based systems that require security updates and can perform controlled deployment of these updates throughout the enterprise with minimal disruption to end users. For more information about how administrators can use SMS 2003 to deploy security updates, visit the SMS 2003 Security Patch Management Web site. SMS 2.0 users can also use Software Updates Service Feature Pack to help deploy security updates. For information about SMS, visit the SMS Web site.

      Note SMS uses the Microsoft Baseline Security Analyzer, the Microsoft Office Detection Tool, and the Enterprise Update Scan Tool to provide broad support for security bulletin update detection and deployment. Some software updates may not be detected by these tools. Administrators can use the inventory capabilities of the SMS in these cases to target updates to specific systems. For more information about this procedure, visit the following Web site. Some security updates require administrative rights following a restart of the system. Administrators can use the Elevated Rights Deployment Tool (available in the SMS 2003 Administration Feature Pack and in the SMS 2.0 Administration Feature Pack) to install these updates.
