Apple has issued a major security update for Mac OS X and Safari, plugging 86 holes and vulnerabilities in 30 different applications for Mac OS, both the "Tiger" and "Leopard" versions. The Safari browser got a separate set of fixes, covering 13 issues, including a remote code execution vulnerability.

The patches cover the full array of Apple's products; both the client and server software and both the Intel and PowerPC versions of the OS all had their share of fixes.

For example, the open-source ClamAV antivirus scanner included in Apple's server operating system received nine fixes. There were also fixes in Leopard's firewall and the Apache server.

Mac users can download the fixes either through Apple's Software Update tool or manually from the Apple Downloads site.
