An authentication bypass vulnerability exists libcurl <8.0.0 in the
connection reuse feature which can reuse previously established connections
with incorrect user permissions due to a failure to check for changes in
the CURLOPT_GSSAPI_DELEGATION option. This vulnerability affects
krb5/kerberos/negotiate/GSSAPI transfers and could potentially result in
unauthorized access to sensitive information. The safest option is to not
reuse connections if the CURLOPT_GSSAPI_DELEGATION option has been changed.
