CVE-2018-1000120
Duy Phan Thanh discovered that curl could be fooled into writing a
zero byte out of bounds when curl is told to work on an FTP URL with
the setting to only issue a single CWD command, if the directory part
of the URL contains a '%00' sequence.

CVE-2018-1000121
Dario Weisser discovered that curl might dereference a near-NULL
address when getting an LDAP URL due to the ldap_get_attribute_ber()
function returning LDAP_SUCCESS and a NULL pointer. A malicious server
might cause libcurl-using applications that allow LDAP URLs, or that
allow redirects to LDAP URLs to crash.

CVE-2018-1000122
OSS-fuzz, assisted by Max Dymond, discovered that curl could be
tricked into copying data beyond the end of its heap based buffer
when asked to transfer an RTSP URL.");
