This rarely used option is used to send variable=content pairs toTELNET servers.Due to flaw in the option parser for sending `NEW_ENV` variables, libcurlcould be made to pass on uninitialized data from a stack based buffer to theserver. Therefore potentially revealing sensitive internal information to theserver using a clear-text network protocol.This could happen because curl did not call and use sscanf() correctly whenparsing the string provided by the application.</p> <p><strong>Affected:</strong> https://github.com/curl/curl</p> <p>curl supports the `-t` command line option, known as `CURLOPT_TELNETOPTIONS`in libcurl.
