Apple on Wednesday released an update to the Safari Web Browser for Mavericks, Mountain Lion, and Lion. Safari 7.0.4 for OS X 10.9, and version 6.1.4 for 10.8 and 10.7, addresses several security vulnerabilities and promises to resolve a memory corruption issue. From Apple’s update notes:
An encoding issue existed in the handling of unicode characters in URLs. A maliciously crafted URL could have led to sending an incorrect postMessage origin. This issue was addressed through improved encoding/decoding.
Multiple memory corruption issues existed in WebKit. These issues were addressed through improved memory handling.
Today’s update arrives about a week after the launch of OS X 10.9.3, which included Safari 7.0.3 for all users who had not previously upgraded.
Users can find the update via the Mac App Store’s Software Update feature, or download it manually using the appropriate link, below. The updates weigh in at around 50MB each.
