Microsoft’s Patch Tuesday updates for July 2018 address more than 50 vulnerabilities, but none of them appear to have been exploited for malicious purposes before the fixes were released.
The company has classified 18 of the flaws as critical and, similar to previous months, they mostly affect the Edge and Internet Explorer web browsers. Many of these security holes have been described as memory corruption bugs that allow remote code execution.
Three of the flaws patched this month were publicly disclosed before Microsoft released patches. The list includes CVE-2018-8278, a spoofing vulnerability affecting Edge; and CVE-2018-8314 and CVE-2018-8313, both of which are Windows privilege escalation vulnerabilities.
