We know that product end-of-life (EoL) brings security risks and the accumulation of vulnerabilities, as manufacturers stop releasing corrective patches. However, starting a replatforming process five years early seems like a perhaps excessive choice.
Microsoft is working to fix a bug in its Defender for Endpoint enterprise security platform that caused the security software to incorrectly report SQL Server 2017 and 2019 as “out of date.”
BleepingComputer reports that the outage affected Defender XDR customers as early as Wednesday morning. Microsoft itself confirms that SQL Server 2019 will be supported until January 2030 and SQL Server 2017 until October 2027.
The error occurred because of a recent code update related to the system for detecting “end of support” (EoL) programs, which are programs whose support period has expired.
As a result, Defender incorrectly marked current versions of SQL Server as obsolete. “Users with SQL Server 2019 and 2017 installed may see incorrect labels in the Threat and Vulnerability Management section. We have already begun deploying a fix that will revert the incorrect changes,” Microsoft reported.
The company clarified that the issue could affect all customers using SQL Server 2017 and 2019, but that it is a limited incident. Microsoft promised to publish a schedule for the full rollout of the fix as soon as it is ready. This isn’t the first time Defender for Endpoint has responded incorrectly to updates.
A week earlier, the product had incorrectly identified the BIOS of some Dell devices as out of date , prompting a nonexistent update.
In early September, the company faced another problem: false positives from its anti-spam service, which prevented Exchange Online and Microsoft Teams users from opening links in emails and chats. It seems Microsoft engineers had a particularly busy autumn.
