1) Key management errors
EUVDB-ID: #VU12732
Risk: Low
CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2018-9234
CWE-ID:
CWE-320 - Key Management Errors

cookies. If the source handle did not read any cookies from a specific
file on disk, the cloned version of the handle would instead store the
file name as none (using the four ASCII letters, no quotes).
none - if such a file exists and is readable in the current directory of the program using libcurl.
