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, leading to denial of service.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://github.com/libical/libical/issues/1361","tags":[]},{"url":"https://github.com/libical/libical/pull/1363","tags":[]},{"url":"https://github.com/libical/libical/pull/1363/changes/557d9c043733b33a8511dce41fdeeb508460d5a9","tags":[]}],"exploitRefs":[{"url":"https://github.com/libical/libical/issues/1361","tags":[]},{"url":"https://github.com/libical/libical/pull/1363","tags":[]},{"url":"https://github.com/libical/libical/pull/1363/changes/557d9c043733b33a8511dce41fdeeb508460d5a9","tags":[]}],"hasPoc":true,"ai":null}
