Apple has posted security updates to fix 16 security vulnerabilities in its Mac OS X operating system. Both client and server versions of the software need patching.

The bugs stem from flaws Apache web server software, QuickTime Streaming Server and Apple's Safari web browser, for example. Security firm Secunia describes the patches as "highly critical".

Left unfixed, crackers could theoretically run amok with vulnerable systems. Even though the vulnerabilities are not been actively exploited they still merit attention. One vulnerability affects at least 25,000 web servers running the Apple Mac OS, according to managed security firm NetSec, which discovered the security bug in Apple's HFS+ filesystem.

Secunia has produced a comprehensive overview of the security bugs, with links to Apple's patches, here. ®
