It’s the second week of October, and Microsoft’s Patch Tuesday happened to be at the beginning of the calendar month. In a way, this month is exceptional for security updates. It is, however, a pleasant exception because there are no particularly critical issues related to vulnerabilities.

However, there was an exception during the last period, as Microsoft published an out-of-band type security update (CVE-2019-1367) outside of the regular Patch Tuesday. The update was a fix for Internet Explorer’s vulnerability on several different Windows operating systems.

October’s Patch Tuesday’s highest CVSS (Common Vulnerability Scoring System) score of 7.8/10 is related to the following vulnerabilities: CVE-2019-1311, CVE-2019-1315, CVE-2019-1325, CVE-2019-1339, CVE-2019-1340, CVE-2019-1341, CVE-2019-1358, and CVE-2019-1359. According to this month’s vulnerability report, there were no zero-day vulnerabilities for Microsoft’s operating system, browser, or Office products. In addition, none of the vulnerabilities were publicly disclosed. For these reasons, none of the vulnerabilities showed any signs that they could be considered as highly critical.

Version 1903 could be considered an exception because this month it had zero issues, and it has been at the top of the list with its high number of issues the last few months. This month’s known issues do not seem to be unreasonable. October updates have the following number of issues.
