Security News > 2020 > May > Apple Patches Over 40 Vulnerabilities in macOS Catalina
Apple this week released security updates to address over fifty vulnerabilities impacting macOS and Safari.
Eighteen of these vulnerabilities are specific to macOS Catalina, but many impact macOS High Sierra and macOS Mojave as well, and patches were released for those platform iterations as well.
What's more, Apple addressed two other vulnerabilities that impact macOS Mojave only, as well as two more that affect macOS Mojave and macOS High Sierra.
All these security bugs were fixed with the release of macOS Catalina 10.15.5, Security Update 2020-003 for Mojave, and Security Update 2020-003 for High Sierra.
Apple also patched 10 vulnerabilities with the rollout of Safari 13.1.1, which is now available for macOS Mojave and macOS High Sierra, and included in macOS Catalina.
