Welcome to this May Patch Monday bulletin. This month we have patches from Adobe, Google and Mozilla with exploits against Adobe Acrobat. Start this month by patching Adobe Acrobat since there are reports that exploits exist for CVE-2018-4990 and CVE-2018-4993. Proof of concept code exists for CVE-2018-4993 and there are reports of attacks against CVE-2018-4990 in the wild. Educate users to spot suspicious emails and safe practices opening documents and evaluate mitigations that are available. Following mitigation recommendations can help stop attacks against CVE-2018-4993 by blocking users from following links in PDF’s. Follow up with Adobe Flash and Chrome or Firefox if they exist in your environment. Review the environment and update Thunderbird and the remaining Adobe products that have patches.

Over the years we've had millions of visitors to UltimateWindowsSecurity.com. Every month we have thousands and thousands of visitors to our Security Log Encyclopedia which documents all of the Security Log event ID’s for Windows Server OS’s. Back in 2007 when SharePoint added auditing capability, I realized that my audience not only needed the event information from SharePoint but I also found a similar need in SQL Server and Exchange. So not only did I document the data but I also started to develop the means to extract that event data from these applications so that it’s accessible and useable to the end user. Some 8 years later and LOGbinder is continuing to grow as companies realize LOGbinder bridges the gap between these applications and their infosec team. Visit LOGbinder.com to download a free 30-day fully functional trial and see the security event data that you have literally been missing.

So, without further ado, here’s the chart of MS patches this month.
