Microsoft’s Patch Tuesday updates for November address more than 50 vulnerabilities, including 20 critical flaws affecting the company’s web browsers.
A total of 53 CVE identifiers have been assigned to the security bugs addressed by Microsoft this month. None of them appear to have been exploited in attacks before the company released the patches.
Three of the flaws have already been publicly disclosed. These are a browser memory corruption that can lead to code execution (CVE-2017-11827), an information disclosure issue in ASP.NET (CVE-2017-8700), and an information disclosure bug in Internet Explorer (CVE-2017-11848).
