Apple plugs browser vulnerabilities with Safari update Featured

By

Apple has released updated versions of its Safari browser for OS X to patch dozens of vulnerabilities.

New versions of Apple's Safari web browser provide bug and security fixes, along with one new feature in the Mavericks version.

Safari 6.1.3 for Lion and Mountain Lion provides the customary "improvements to compatibility, stability and security."

Specific changes called out by Apple are a fix for an issue that could cause the search and address field to load a webpage or send a search term before the return key is pressed, support for generic top-level domains (so that Safari loads the requested page instead of treating it as a search term), and strengthened Safari sandboxing.

Safari 7.0.3 for Mavericks contains similar changes plus one new feature - the ability to completely block sites from requesting permission to send push notifications.

The updates address 26 vulnerabilities in WebKit that could allow arbitrary code execution.

More than half were discovered by the Google Chrome Security Team, but some surfaced in recent security competitions.

A further WebKit vulnerability discovered by Ian Beer of Google Project Zero made it possible to bypass sandbox restrictions to read arbitrary files.

Details of the security content will be available at Apple security updates.

Safari 6.1.3 is available via Software Update for Lion or the Mac App Store for Mountain Lion, and Safari 7.0.3 is available via the Mac App Store.

Safari was last updated in February, alongside the release of OS X Mavericks 10.9.2.
