Microsoft has rolled out fixes for its Windows operating system and other software components to remediate major security shortcomings as part of Patch Tuesday updates for June 2023.
Of the 73 flaws, six are rated Critical, 63 are rated Important, two are rated Moderate, and one is rated Low in severity. This also includes three issues the tech giant addressed in its Chromium-based Edge browser.
It's worth noting that Microsoft also closed out 26 other flaws in Edge – all of them rooted in Chromium itself – since the release of May Patch Tuesday updates. This comprises CVE-2023-3079, a zero-day bug that Google disclosed as being actively exploited in the wild last week.
The June 2023 updates also mark the first time in several months that doesn't feature any zero-day flaw in Microsoft products that's publicly known or under active attack at the time of release.
Topping the list of fixes is CVE-2023-29357 (CVSS score: 9.8), a privilege escalation flaw in SharePoint Server that could be exploited by an attacker to gain administrator privileges.
