Vadim Penzin).
* Bugfixes
- Fixed POLLIN|POLLHUP condition handling error resulting
in prematurely closed (truncated) connection.

"transparent = destination" functionality (thx to
Vadim Penzin). This bug was introduced in stunnel 5.00.

as the -fd commandline option parameter.
- A number of minor Win32 GUI bugfixes and improvements.
- Merged most of the Windows CE patches (thx to Pierre Delaage).
- Fixed incorrect CreateService() error message on Win32.
- Implemented a workaround for defective Cygwin file
descriptor passing breaking the libwrap support:

instead of the original resources to prevent the resources
from being destroyed.

str_realloc().

Version 5.03, 2014.08.07, urgency: HIGH:
* Security bugfixes
- OpenSSL DLLs updated to version 1.0.1i.
See https://www.openssl.org/news/secadv_20140806.txt
* New features
- FIPS autoconfiguration cleanup.
- FIPS canister updated to version 2.0.6.
- Improved SNI diagnostic logging.
* Bugfixes
- Compilation fixes for old versions of OpenSSL.
- Fixed whitespace handling in the stunnel.init script.
Version 5.02, 2014.06.09, urgency: HIGH:
* Security bugfixes
- OpenSSL DLLs updated to version 1.0.1h.
See https://www.openssl.org/news/secadv_20140605.txt
* New features
- Major rewrite of the protocol.c interface: it is now possible to add
protocol negotiations at multiple connection phases, protocols can
individually decide whether the remote connection will be
established before or after SSL/TLS is negotiated.
- Heap memory blocks are wiped before release. This only works for
block allocated by stunnel, and not by OpenSSL or other libraries.
- The safe_memcmp() function implemented with execution time not
dependent on the compared data.
- Updated the stunnel.conf and stunnel.init templates.
- Added a client-mode example to the manual.
* Bugfixes
- Fixed "failover = rr" broken since version 5.00.
- Fixed "taskbar = no" broken since version 5.00.
- Compilation fix for missing SSL_OP_MSIE_SSLV2_RSA_PADDING option.
Do it for all packages that
* mention perl, or
* have a directory name starting with p5-*, or
* depend on a package starting with p5-
like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.
Changelog:
Version 5.01, unreleased, urgency: HIGH:
* Security bugfixes
- OpenSSL DLLs updated to version 1.0.1g.
This version mitigates TLS heartbeat read overrun (CVE-2014-0160).
* New features
- X.509 extensions added to the created self-signed stunnel.pem.
- "FIPS = no" also allowed in non-FIPS builds of stunnel.
- Search all certificates with the same subject name for a matching
public key rather than only the first one (thx to Leon Winter).
- Create logs in the local application data folder if stunnel folder
is not writable on Win32.
* Bugfixes
- close_notify not sent when SSL still has some data buffered.
- Protocol negotiation with server-side SNI fixed.
- A Mac OS X missing symbols fixed.
- Win32 configuration file reload crash fixed.
- Added s_pool_free() on exec+connect service retires.
- Line-buffering enforced on stderr output.
Of utmost importance: it fixes CVE 2014-0016.
Thanks to jgw (Jeff W) _AT_ sdf.org for working on the same patch
independently.
In before the freeze! Changelog follows.
Security bugfixes
Added PRNG state update in fork threading (CVE-2014-0016).
New global configuration file defaults
Default "fips" option value is now "no", as FIPS mode is only helpful for compliance, and never for actual security.
Default "pid" is now "", i.e. not to create a pid file at startup.
New service-level configuration file defaults
Default "ciphers" updated to "HIGH:MEDIUM:+3DES:+DH:!aNULL:!SSLv2" due to AlFBPPS attack and bad performance of DH ciphersuites.
Default "libwrap" setting is now "no" to improve performance.
New features
OpenSSL DLLs updated to version 1.0.1f.
zlib DLL updated to version 1.2.8.
autoconf scripts upgraded to version 2.69.
TLS 1.1 and TLS 1.2 are now allowed in the FIPS mode.
New service-level option "redirect" to redirect SSL client connections on authentication failures instead of rejecting them.
New global "engineDefault" configuration file option to control which OpenSSL tasks are delegated to the current engine. Available tasks: ALL, RSA, DSA, ECDH, ECDSA, DH, RAND, CIPHERS, DIGESTS, PKEY, PKEY_CRYPTO, PKEY_ASN1.
New service-level configuration file option "engineId" to select the engine by identifier, e.g. "engineId = capi".
New global configuration file option "log" to control whether to append (the default), or to overwrite log file while (re)opening.
Different taskbar icon colors to indicate the service state.
New global configuration file options "iconIdle", "iconActive", and "iconError" to select status icon on GUI taskbar.
Removed the limit of 63 stunnel.conf sections on Win32 platform.
Installation of a sample certificate was moved to a separate "cert" target in order to allow unattended (e.g. scripted) installations.
Reduced length of the logged thread identifier. It is still based on the OS thread ID, and thus not unique over long periods of time.
Improved readability of error messages printed when stunnel refuses to start due to a critical error.
Bugfixes
LD_PRELOAD Solaris compatibility bug fixed (thx to Norm Jacobs).
CRYPTO_NUM_LOCKS replaced with CRYPTO_num_locks() to improve binary compatibility with diverse builds of OpenSSL (thx to Norm Jacobs).
Corrected round-robin failover behavior under heavy load.
Numerous fixes in the engine support code.
On Win32 platform .rnd file moved from c:\ to the stunnel folder.
- Fixed a regression bug introduced in version 4.55 causing random
crashes on several platforms, including Windows 7.
- Fixed incorrect "stunnel -exit" process synchronisation.
- Fixed FIPS detection with new versions of the OpenSSL library.
- Failure to open the log file at startup is no longer ignored.
a) refer 'perl' in their Makefile, or
b) have a directory name of p5-*, or
c) have any dependency on any p5-* package
Like last time, where this caused no complaints.
