Apple bug hunters turn attention to AppleTalk

Your IT - Home IT

The Month of Apple Bugs broke fresh ground today, highlighting a buffer overflow in Mac OS X's AppleTalk stack.

According to LMH, insufficient checking by a particular function "leads to a denial of service condition and potential arbitrary code execution by unprivileged users. Remote exploitation might be possible".

The proof of concept just causes a kernel panic.

Yesterday's bug was another DMG (disk image file) exploit, this time using a malformed HFS+ filesystem. Like the previous exploit, it carries a risk that other mounted filesystems may be corrupted. The outcome of that is more likely to be serious than with the UFS exploit, as most Mac hard drives use HFS+.

Landon Fuller of the MoAB Fixes group is disinclined to offer kernel patches (the filesystem and AppleTalk issues are kernel related), writing "The stakes are much higher when patching the kernel... I don't want to provide a cure that's worse than the disease."

The group is continuing work on a utility to 'sanity check' DMGs prior to mounting them.
