SELinux Isn’t Scary
Back in the before times, during the era of RHEL/CentOS 4, SELinux was barely worth the security it offered. It was unwieldy, caused access problems even in Permissive mode, and the command line tools and documentation were esoteric at best when they even existed.
It’s been a few years since that time, however, and significant development has been done to get SELinux into a much more usable and user-friendly state. At this point, most of the fears surrounding SELinux are based on old experiences, and it behooves everyone to re-examine those fears to see if they’re still realistic.
Usability often has to trump security. As an example, we now have the ability to just tap a credit card on a machine and have the purchase approved. There are significant security risks involved, but as long as those risks are known and minimized (for example, by limiting the amount that can be purchased in this way), usability can win.

The Windows January 2019 Update was the cause behind the bug, Microsoft confirmed today. Microsoft added the Access 97 bug to the “known issue” section. The January update aimed to fix a vulnerability in Jet Database Engine shipped with Windows. “As a result of this patch, open databases in Access 97 MDB format fail with a database error “unknown database format” – if the database contains field names with a length greater than 32 characters”, as Borncity reports. While this bug only affects Microsoft.Jet.OLEDB.4.0 providers, there were only a few workarounds. Microsoft added the following paragraph to the known issue section, highlighting the bug.
