Use-after-free vulnerability in Apple iCal 3.0.1 on Mac OS X allows remote CalDAV servers, and user-assisted remote attackers, to trigger memory corruption or possibly execute arbitrary code via an "ATTACH;VALUE=URI:S=osumi" line in a .ics file, which triggers a "resource liberation" bug. NOTE: CVE-2008-2007 was originally used for this issue, but this is the appropriate identifier.
Apple iCal 3.0.1 on Mac OS X allows remote CalDAV servers, and user-assisted remote attackers, to cause a denial of service (NULL pointer dereference and application crash) or possibly execute arbitrary code via a .ics file containing (1) a large 16-bit integer on a TRIGGER line, or (2) a large integer in a COUNT field on an RRULE line.
