Mike Salvatore discovered that FlightCrew improperly handled certain malformed EPUB files. An attacker could potentially use this vulnerability to cause a denial of service. (CVE-2019-13032)
Mike Salvatore discovered that FlightCrew mishandled certain malformed EPUB files. An attacker could use this vulnerability to write arbitrary files to the filesystem. (CVE-2019-13241)
Mike Salvatore discovered that the version of Zipios included in FlightCrew mishandled certain malformed ZIP files. An attacker could use this vulnerability to cause a denial of service or consume system resources. (CVE-2019-13453).
