2018-09-07  Tomas Hozza  <thozza@redhat.com>

	Add TLS 1.3 support for GnuTLS
	* doc/wget.texi: Add "TLSv1_3" to --secure-protocol
	* src/gnutls.c (set_prio_default): Use GNUTLS_TLS1_3 where needed

	Wget currently allows specifying "TLSv1_3" as the parameter for
	--secure-protocol option. However it is only implemented for OpenSSL
	and in case wget is compiled with GnuTLS, it causes wget to abort with:
	GnuTLS: unimplemented 'secure-protocol' option value 6

	GnuTLS contains TLS 1.3 implementation since version 3.6.3 [1]. However
	currently it must be enabled explicitly in the application of it to be
	used. This will change after the draft is finalized. [2] However for
	the time being, I enabled it explicitly in case "TLSv1_3" is used with
	--secure-protocol.

	I also fixed man page to contain "TLSv1_3" in all listings of available
	parameters for --secure-protocol

	url_escape() really returns a newly allocated memory and it leaks when the warc_write_cdx_record() returns. The memory returned from url_escape() is usually stored in a temporary variable in other parts of the project and then freed. I took the same approach.

	* src/warc.c (warc_write_start_record): Fix potential RESOURCE LEAK
	In warc_write_start_record() function, the reutrn value of dup() is
	directly used in gzdopen() call and not stored anywhere. However the
	zlib documentation says that "The duplicated descriptor should be saved
	to avoid a leak, since gzdopen does not close fd if it fails." [1].
	This change stores the FD in a variable and closes it in case gzopen()
	fails.

	Both "pth" and "auth_stat" are allocated in "check_auth()" function. These are used for creating the HTTP Authorization Request header via "create_authorization_line()" function. In case the creation went OK (auth_err == RETROK), then the memory previously allocated to "pth" and "auth_stat" is freed. However if the creation failed, then the memory is never freed and it leaks.

	* src/ftp.c (getftp): Fix RESOURCE LEAK found by Coverity
	Error: RESOURCE_LEAK (CWE-772):
	wget-1.19.5/src/ftp.c:1493: alloc_fn: Storage is returned from allocation function "fopen".
	wget-1.19.5/src/ftp.c:1493: var_assign: Assigning: "fp" = storage returned from "fopen(con->target, "wb")".
	wget-1.19.5/src/ftp.c:1811: leaked_storage: Variable "fp" going out of scope leaks the storage it points to.
	\# 1809|     if (fp && !output_stream)
	\# 1810|       fclose (fp);
	\# 1811|->   return err;
	\# 1812|   }
	\# 1813|

	It can happen, that "if (!output_stream || con->cmd & DO_LIST)" on line #1398 can be true, even though "output_stream != NULL". In this case a new file is opened to "fp". Later it may happen in the FTPS branch, that some error will occure and code will jump to label "exit_error". In "exit_error", the "fp" is closed only if "output_stream == NULL". However this may not be true as described earlier and "fp" leaks.

	On line #1588, there is the following conditional free of "fp":

	  /* Close the local file.  */
	  if (!output_stream || con->cmd & DO_LIST)
	    fclose (fp);

	Therefore the conditional at the end of the function after "exit_error" label should be modified to:

	  if (fp && (!output_stream || con->cmd & DO_LIST))
	    fclose (fp);

	This will ensure that "fp" does not leak in any case it sould be opened.

	Don't limit the test suite HTTPS server to TLSv1
	In Fedora, we are implementing crypto policies, in order to enhance the
	security of user systems. This is done on the system level by global
	configuration. It may happen that due to the active policy, only
	TLSv1.2 or higher will be available in crypto libraries. While wget as
	a client will by default determine the minimal TLS version supported by
	both client and server, the HTTPS server implementation in testenv/
	hardcodes use of TLSv1. As a result all HTTPS related tests fail in
	case a more hardened crypto policy is set on the Fedora system.

	This change removes the explicit TLS version setting and leaves the
	determination of the minimal supported TLS version on the server and
	client.

	More information about Fedora change can be found here:
	https://fedoraproject.org/wiki/Changes/StrongCryptoSettings

	Enhance SSL/TLS security
	This commit hardens SSL/TLS a bit more in the following ways:

	 * Explicitly exclude NULL authentication and the 'MEDIUM' cipher list
	   category. Ciphers in the 'HIGH' level are only considered - this
	   includes all symmetric ciphers with key lengths larger than 128 bits,
	   and some ('modern') 128-bit ciphers, such as AES in GCM mode.
	 * Allow RSA key exchange by default, but exclude it when
	   Perfect Forward Secrecy is desired (with --secure-protocol=PFS).
	 * Introduce new option --ciphers to set the cipher list that the SSL/TLS
	   engine will favor. This string is fed directly to the underlying TLS
	   library (GnuTLS or OpenSSL) without further processing, and hence its
	   format and syntax are directly dependent on the specific library.
