"The 10.5.7 Update is recommended for Mac OS X 10.5 Leopard and includes general operating system fixes that enhance the stability, compatibility and security of your Mac. For detailed information about security updates, please visit this website."

Nothing in this update too compelling for me; for the most part I'm not needing any of the fixes offered.  I'll upgrade anyway, but this one seems like a relatively minor one to me.  Maybe I'm missing something?

Malicious code execution exploits in Safari 4 beta, Safari 3, CoreGraphics when opening PDF files, multiple vulnerabilities in Flash player plug-in, a local user can obtain system privileges in the kernel, etc.?

I'd surely update!

(I have, everything seems to be running fine so far.)

One thing that I noticed yesterday is that if you are running the Safari 4 beta, there is a second update that is available after you install the 10.5.7 update. That particular update is not packaged with 10.5.7.
