Description

Dario Weisser discovered that curl incorrectly handled long FTP server command replies. If a user or automated system were tricked into connecting to a malicious FTP server, a remote attacker could use this issue to cause curl to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 17.10 and Ubuntu 18.04 LTS. (CVE-2018-1000300)
