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 get access to sensitive data. (CVE-2018-1000122).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
