Apple has released Safari 12.0.3 for macOS 10.13.6 High Sierra and 10.12.6 Sierra to address several security vulnerabilities. The new version prevents maliciously crafted Web content from leading to a cross-site scripting attack and improves memory handling to thwart arbitrary code execution. In addition, readers are reporting that 12.0.3 may also fix problems with crashes related to accessing .webloc files (what you get when you drag a URL from Safari to the Finder) in Sierra. Let us know in the comments if you’re still seeing issues with .webloc files in Sierra. Safari 12.0.3 is available only via Software Update. (Free, release notes, macOS 10.13.6 and 10.12.6)
