Apple rolls out 31 patches for Mac OS X

The Mac OS X patches fix components ranging from the Address Book and iChat software to under-the-covers operating system components such as ColorSync, the IO Storage Family, and the Perl, Python and Ruby programming languages.

Most of these flaws theoretically could be exploited by attackers to run unauthorized software on the Mac, although some of them had other security implications, such as allowing an attacker to gain access to sensitive information or download files to the computer without authorization.
