Multiple vulnerabilities have been identified in Apple iCal, which could be exploited by attackers to cause a denial of service or potentially compromise a vulnerable system. These issues are caused by NULL pointer derefence and memory corruption errors when processing ICS files containing a malformed "COUNT", "TRIGGER" or "ATTACH" field, which could be exploited by attackers to crash an affected application or potentially execute arbitrary code by tricking a user into opening a specially crafted file.
