- CVE-2016-9584Critical
Libical allows remote attackers to cause a denial of service (use-after-free) and possibly read heap memory via a crafted ics file.
- CVE-2026-88383Medium
libical 4.0.6 contains an incompatible function pointer in icalparameter_string_to_kind(). When parsing iCalendar data containing a parameterized property, the function passes icalparameter_compare_kind_map() to bsearch() through an incompatible comparator function pointer type. bsearch() invokes the callback through the mismatched type, resulting in undefined behavior and process termination.
