Security experts at Sophos have urged users of the Apple Mac OS X operating system to install an important new security update.
Apple has issued the new security update, which fixes a number of flaws in the Mac OS X operating system that could be exploited by malicious hackers or malware. The vulnerabilities, if left unpatched, could allow hackers to run dangerous code on innocent unprotected computers.
The security update affects the following Mac OS X components:
Amongst the fixes is an update to the Safari web browser which was found to be vulnerable to malicious shell scripts. Additionally the iChat instant messaging system has been updated to warn of potentially malicious file types being transmitted. The update to iChat has been issued in the wake of the discovery of the OSX/Leap-A worm last month.
Separate downloads are available on Apple's web site for Mac OS X v10.3.9 "Panther" client and server versions, as well as Mac OS X v10.4.5 "Tiger" Intel and PowerPC versions.
