SQL Server vulnerability warning from Microsoft

Microsoft has issued an advisory confirming a remote code execution vulnerability affecting its SQL Server line.

The vulnerability affects Microsoft SQL Server 2000, Microsoft SQL Server 2005, Microsoft SQL Server 2005 Express Edition, Microsoft SQL Server 2000 Desktop Engine (MSDE 2000), Microsoft SQL Server 2000 Desktop Engine (WMSDE), and Windows Internal Database (WYukon). Microsoft said systems with Microsoft SQL Server 7.0 Service Pack 4, Microsoft SQL Server 2005 Service Pack 3, and Microsoft SQL Server 2008 are not affected by this issue.

Microsoft's advisory said: "Microsoft is aware that exploit code has been published on the internet for the vulnerability addressed by this advisory. Our investigation of this exploit code has verified that it does not affect systems that have had the workarounds listed below applied. Currently, Microsoft is not aware of active attacks that use this exploit code or of customer impact at this time."

"In addition, due to the mitigating factors for default installations of MSDE 2000 and SQL Server 2005 Express, Microsoft is not currently aware of any third-party applications that use MSDE 2000 or SQL Server 2005 Express which would be vulnerable to remote attack. However, Microsoft is actively monitoring this situation to provide customer guidance as necessary."

Microsoft said it was unaware of any active attacks utilising the exploit code.

The advisory comes less than a week after Microsoft released a critical security patch to plug vulnerabilities in Internet Explorer amid malicious attackers taking advantage of the security flaws.
