Microsoft pulls the Cumulative Update package 7 (CU7) for SQL Server 2019 released on September 2. Microsoft confirmed a known reliability issue impacting customers who used the database snapshot feature. The issue does not result in a memory dump or an SQL service crash when generating snapshots. Microsoft removed the ability to download files using Windows Defender after it was illustrated how it could be used by threat actors to download malware onto a victim’s computer. Microsoft is planning to include a fix for this known issue in the latest version of its software.
