Original advisory details:

 Phan Thanh discovered that curl incorrectly handled certain FTP paths. An
 attacker could use this to cause a denial of service or possibly execute
 arbitrary code. (CVE-2018-1000120)

 Dario Weisser discovered that curl incorrectly handled certain LDAP URLs.
 An attacker could possibly use this issue to cause a denial of service.
 (CVE-2018-1000121)

 Max Dymond discovered that curl incorrectly handled certain RTSP data. An
 attacker could possibly use this to cause a denial of service or even to
