Yesterday, apple released a new set of security patches for OS X. Note that some of them fix arbitrary code execution problems in Safari and Mail.

All Apple wants you to know about the patches can be found here:

Our testing hasn't shown any problems so far. Please report any issues you might have. The list of patches is long, and they can only be applied as a set, so we will skip a discussion of individual issues.
