CVE-2008-2006

Status: ModifiedMedium (4.3)—

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.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
