For the fourth successive month, Microsoft Patch Tuesday has seen more than 100 CVEs patched and June 2020 Patch Tuesday contains the biggest round of updates ever issued. Microsoft has released updates to correct 129 vulnerabilities. That breaks the record set in March when patches were released to correct 115 vulnerabilities.
This month’s update includes patches for 11 critical vulnerabilities, although none are currently being exploited in real world attacks. 109 vulnerabilities are classed as important, with 7 rated as moderate and 2 as low severity. 98 of the vulnerabilities are for operating systems and browsers, with the remainder spread across a range of different Microsoft products.
Applying the patches across all devices can be a challenge at the best of times, but even more so with so many employees working from home with slow internet connections. Priority should be given to the following vulnerabilities, with the Windows OLE and Microsoft SharePoint patches two of the most important.
