Don't miss a single vulnerability this Patch Tuesday. The latest patches and updates from Microsoft and multiple third-party applications can be found in June's Patch Tuesday Index below.

Microsoft addressed 49 vulnerabilities in this month’s Patch Tuesday update. While the number of vulnerabilities in June was only 5 fewer than May, it represents 33% fewer vulnerabilities on average for each month so far this year. Of those vulnerabilities, 5 were rated as critical, the same as last month, and 52% lower on average. Unfortunately, 6 vulnerabilities are being actively exploited in the wild, equaling the highest number seen so far this year.

Earlier in the month, Mozilla released updates for Thunderbird, Firefox, Firefox ESR, and Firefox for iOS. Of the four security bulletins, only the Firefox 89 advisory was rated High.

Adobe released security updates for 10 products. Each bulletin received Adobe Priority Rating 3, except for the bulletins relating to Acrobat & Reader and Experience Manager which were raised to Priority Rating 2.
