Apple announced in a notice on its corporate Web site, it had released a wrap-up of general operating system stability and security improvements, including several that address malicious crafting exploits.

One new security update released today and incorporated into the version 10.5.4 package addresses a series of problems uncovered by, and attributed to, UK-based software developer and consultant James Urquhart, who himself does not claim to be a security engineer. A recent Secunia software advisory also credits Urquhart, who was also able to locate a problem with versions of Safari for Windows prior to version 3.1.2 (obviously not addressed by today's Mac OS X update).
