Apple OSX and Safari Updates
Apple released security updates for the Safari browser and currently supported versions of its operating system, OSX 10.8, 10.7, and 10.6. (Users of OSX 10.5 and earlier should consider upgrading to a more recent version to continue receiving security updates.) These updates address a number of vulnerabilities that could allow remote code execution.
ITS recommends that you keep your computers and other devices up to date with the latest security fixes in order to protect your machines and your data from malicious code and unauthorized access.
