Welcome to Database Patch News, Buda Consulting’s newsletter of current patch information for Oracle and Microsoft SQL Server. Here you’ll find information recently made available on patches—including security patches—and desupported versions.

Why should you care about patching vulnerabilities and bugs? Two big reasons:

  1. Unpatched systems are a top cyberattack target. Patch releases literally advertise vulnerabilities to the hacker community. The longer you wait to patch, the greater your security risk. 
  2. Along with running a supported database version, applying the latest patches ensures that you can get support from the vendor in case of an issue. Patching also helps eliminate downtime and lost productivity associated with bugs. 

Here are the latest patch updates for Oracle and SQL Server:
