Apple has pushed out an update for Safari for Mac today that addresses a few of security issues with WebKit.

The update applies to Safari on OS X Yosemite, Mavericks, and Mountain Lion, clocking in at version 8.0.6, 7.1.6, and 6.2.6, respectively. Here's the full breakdown of the issues these updates address:

WebKit

Impact: Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution

Description: Multiple memory corruption issues existed in WebKit. These issues were addressed through improved memory handling.

WebKit History

Impact: Visiting a maliciously crafted website may compromise user information on the filesystem

Description: A state management issue existed in Safari that allowed unprivileged origins to access contents on the filesystem. This issue was addressed through improved state management.

WebKit Page Loading

Impact: Visiting a malicious website by clicking a link may lead to user interface spoofing

Description: An issue existed in the handling of the rel attribute in anchor elements. Target objects could get unauthorized access to link objects. This issue was addressed through improved link type adherence.

The updates should hit the Mac App Store and be ready for download relatively soon.
