Why You Should Care?
Warning
These vulnerabilities are flaws that have been identified in Microsoft software, and now that they are publicly known, attackers will try to exploit as many targets as possible before users apply the fix. This makes it extra dangerous, and needs to be addressed as soon as possible.
In this case, one zero-day vulnerability is being actively exploited or publicly disclosed, which means it is only a matter of time before the attackers compromise your business. Now that patches are available, it is critical to apply the patches as soon as possible to avoid getting compromised.
What Should You Do?
- Test the patches ASAP at your organization, and make sure they do not break any business applications
- Prioritize the zero-day vulnerability
- Roll out the rest of the Patch Tuesday updates
