libical 1.0 allows remote attackers to cause a denial of service (use-after-free) via a crafted ics file (CVE-2016-5824). The icaltime_from_string function in libical 0.47 and 1.0 allows remote attackers to cause a denial of service (out-of-bounds heap read) via a crafted string to the icalparser_parse_string function (CVE-2016-5827). libical allows remote attackers to cause a denial of service (use-after-free) and possibly read heap memory via a crafted ics file (CVE-2016-9584).
