discovered a few more minor security issues in Mac OS X that mainly pertain to how the OS and a few of its apps handle
images and opening zip archives. From a quick glance through the listed errors, they pretty much amount to crashing an
app, though a couple of the Safari issues cause "the application to crash, and or may allow for an attacker to
execute arbitrary code."
Apple has been notified of the issues and will apparently be fixing them in the next security update. As Tim Gaden at Hawk Wings (where I found this) says: the classic advice of being careful about what attachments and links you open and click on should keep your Mac humming along just fine.
