Curl 7.40.0 < 8.20.0 Wrong SMB Connection Reuse

The version of curl installed on the remote host is 7.40.0 prior to 8.20.0. It is, therefore, affected by a wrong SMB connection reuse vulnerability: - libcurl might in some circumstances reuse the wrong connection for SMBS transfers. The code erroneously did not consider the share name as a...
