path: root/libotr/libotr-4.1.1/ChangeLog

2016-03-07

	* tests/regression/client/Makefile.am:
	* tests/unit/Makefile.am: Add LIBGCRYPT_CFLAGS to the test suite

	* Makefile.am:
	* configure.ac: Only build the test suite on Linux, since it
	currently uses Linux-specific features such as epoll

2016-03-06

	* Makefile.am: Add bootstrap to the tarball

2016-03-04

	* README:
	* configure.ac:
	* src/version.h: Bump version number to 4.1.1

2016-03-03

	* src/proto.c (otrl_proto_accept_data):
	* src/proto.c (otrl_proto_fragment_accumulate):
	* src/proto.c (otrl_proto_fragment_create): Prevent integer
	overflow on 64-bit architectures when receiving 4GB messages.
	In several places in proto.c, the sizes of portions of incoming
	messages were stored in variables of type int or unsigned int
	instead of size_t.  If a message arrives with very large
	sizes (for example unsigned int datalen = UINT_MAX), then
	constructions like malloc(datalen+1) will turn into malloc(0),
	which on some architectures returns a non-NULL pointer, but
	UINT_MAX bytes will get written to that pointer.  Ensure all
	calls to malloc or realloc cannot integer overflow like this.
	Thanks to Markus Vervier of X41 D-Sec GmbH
	<markus.vervier@x41-dsec.de> for the report.

	* Protocol-v3.html: Clarify that instance tags and fragment
	numbers in the OTR fragment format are allowed to have leading
	0s.  Also fix that how to handle v2 versus v3 messages for the
	Reveal Signature and Signature messages was missing.  Thanks to
	Ola Bini <obini@thoughtworks.com> for the report.

2015-12-25

	* src/instag.c (otrl_instag_read_FILEp): Fix memory leak in
	otrl_instag_read_FILEp if the tag file is malformed.  Thanks to
	Jean-Philippe Aumasson <jeanphilippe.aumasson@gmail.com> for the
	report.

2015-08-18

	* src/message.c (otrl_message_receiving):
	* src/proto.c (otrl_proto_create_data): Set to NULL the sendsmp
	pointer when handling SMP to avoid a potential free() of an
	uninitialized pointer.  Also ensure the message pointer is set
	to NULL in otrl_proto_create_data for extra precaution and to
	prevent future code paths from having the same error.  Thanks to
	Nicolas Guigo <nicolas.guigo@nccgroup.trust> and Ben Hawkes
	<hawkes@inertiawar.com> for the report.

2015-02-08

	* Protocol-v3.html: Typo fixes, thanks to Hannes Mehnert
	<hannes@mehnert.org> and Nadim Kobeissi <nadim@nadim.computer>
	for the reports.

	* src/message.c: Be stricter about parsing v3 fragments.  Thanks
	to Jean-Philippe Aumasson <jeanphilippe.aumasson@gmail.com> for
	the report.

2014-12-18

	* Protocol-v3.html: Remove "sender_instance, receiver_instance,"
	from description of v2 fragmentation and clarify that you can't
	fragment a fragment.  Thanks to Hannes Mehnert
	<hannes@mehnert.org> for the report.

	* Protocol-v3.html: Remove a stray "DRAFT" from the <title> tag.

	* Protocol-v2.html:
	* Protocol-v3.html: Clarify the DSA computation in the protocol
	specs.  Thanks to Adam Langley <agl@imperialviolet.org> and
	Hannes Mehnert <hannes@mehnert.org> for the report.

2014-11-29

	* README:
	* Makefile.am:
	* configure.ac:
	* tests/*: Brand new testsuite, thanks to
	David Goulet <dgoulet@ev0ke.net> and
	Julien Voisin <julien.voisin@dustri.org>.
	"make check" to run it.

2014-11-11

	* b64.c (otrl_base64_otr_encode): In case some future code path
	tries to call otrl_base64_otr_encode with a buffer more than
	3/4 the size of all addressable memory, return NULL rather than
	causing an integer overflow and a heap overrun.  Thanks to
	David Remahl <david@remahl.se> for the report.
	* proto.c (otrl_proto_create_data): Tiny refactor to call
	otrl_base64_otr_encode instead of duplicating the code here.

2014-10-18

	* README:
	* configure.ac:
	* src/version.h: Bump version number to 4.1.0

2014-10-18

	* Protocol-v3.html: Correctly count the number of actions an OTR

	otrl_context_find_recent_instance and
	otrl_context_find_recent_secure_instance.

2014-10-13

	* src/context.c (otrl_context_forget): Correct check for
	children contexts' state being OTRL_MSGSTATE_PLAINTEXT.  Thanks
	to k007k <k007k@wp.pl> for the report.

2014-10-13

	* src/message.c (otrl_message_receiving): Fix memory leak in
	fragment reassembly.  Thanks to Matthew D. Green
	<matthewdgreen@gmail.com> for the report and David Goulet
	<dgoulet@ev0ke.net> for the patch.

2014-10-13

	* src/message.c (otrl_message_sending): Fix possible memory

2014-06-12

	* src/message.h: Typo fix.

2014-06-03

2014-05-22

	* README:
	* src/context.c: Typo fixes.

2014-05-04

	* INSTALL:

	Thanks to David Goulet <dgoulet@ev0ke.net> for the patch.

2014-05-04

	* src/dh.c:
	* src/sm.c:
	* toolkit/sesskeys.c: Use gcrypt secure memory allocation.
	Thanks to Julien Voisin <julien.voisin@dustri.org> for the
	patch.

2014-04-21

	* src/mem.c (otrl_mem_differ): Simplify otrl_mem_differ.  Thanks
	to Julien Voisin <julien.voisin@dustri.org> for the patch.

2014-02-20

	* src/proto.c (otrl_proto_instance): Fix a memory leak when
	receiving an invalid instance tag.  Thanks to Julien Voisin
	<julien.voisin@dustri.org> for the patch.

2014-02-15

	* src/proto.c:
	* src/auth.c:
	* src/mem.c:
	* src/mem.h: Use a constant-time memory comparison for safety.
	Thanks to jvoisin <julien.voisin@dustri.org> for the suggestion.

2013-10-13

	* src/proto.c: Return 0 instead of crashing from
	otrl_proto_query_bestversion if passed an illegal input.
	Thanks to Conrad Hoffmann <ch@bitfehler.net> for the report and
	the patch.

2013-08-21

	* src/proto.c: Fix warning from clang in proto.c. Before, trying
	to fragment a message into more than 65535 pieces would cause
	incorrect fragments to be output.  Now, it just returns an error
	(as that is disallowed by the spec).  Thanks to Teemu Huovila
	<thuovila@cs.helsinki.fi> for reporting the issue.

2013-08-08

	* Protocol-v3.html: Random exponents in SMP should be 1536 bits.
	The spec (but not the code) incorrectly said "128 bits" before.

2013-07-28

	* packaging/fedora/libotr.spec: Fedora spec file for 4.x from
	Paul Wouters <paul@cypherpunks.ca>

2013-07-17

	* toolkit/sesskeys.c: Workaround for a crash bug in libgcrypt
	affecting otr_sesskeys.  Passing a private key value of 0 to
	otr_sesskeys would cause libgcrypt to crash in gcry_mpi_powm.
	We reported this libgcrypt bug and it was then fixed in
	http://lists.gnupg.org/pipermail/gcrypt-devel/2013-July/002251.html
	but the workaround is simply to use
	gcry_mpi_new(DH1536_MOD_LEN_BITS) instead of gcry_mpi_new(0).
	Note that this only affected the otr_sesskeys toolkit program,
	and not libotr itself.
	Thanks to the Mayhem Team at CMU (Alexandre Rebert, Thanassis
	Avgerinos, Sang Kil Cha, David Brumley, Manuel Egele) for the
	report.

2013-01-19

	* src/message.c: pass opdata when sending message fragment
	The inject_message callback was missing the opdata when sending
	message fragments.  Thanks to David Goulet <dgoulet@ev0ke.net>
	for the report.

2012-12-18

	* src/message.c: Copy lastmessage to the newly created context.
	This fixes a case where the first user message gets lost when
	OTRL_POLICY_REQUIRE_ENCRYPTION policy is set because after
	establishing the encryption lastmessage remains with the master
	context and will not be resent.  Thanks to Andreas Schlick
	<schlick@lavabit.com> for the report.

2012-09-09

	* configure.ac: Make linker hardening [DEP, ALSR] work on
	Windows builds.  Thanks to Daniel Atallah <datallah@pidgin.im>
	for noticing that it wasn't working before.

2012-09-04

	* README: Release 4.0.0

2012-08-28

	* UPGRADING:
	* src/proto.h:
	* src/proto.c: Don't have otrl_init call exit(1) if the
	application's requested version number differs from libotr's.
	Rather, return a non-zero error code, and have the application
	clean up gracefully.  The OTRL_INIT macro now checks the error
	code and does an exit(1) as the default behaviour, but the
	application can do what it likes.

2012-08-27

	* src/auth.h:
	* src/auth.c:
	* src/message.c: Record the time the last COMMIT was sent from a
	master context.  This will be used to clear the committed key
	from the master context once we don't expect any more instances
	of our buddy to respond with a DHKEY message.

	* UPGRADING:
	* src/userstate.h:
	* src/userstate.c:
	* src/message.h:
	* src/message.c: Add a timer_control callback to
	OtrlMessageAppOps in order to actually clear out the above stale
	committed keys.

2012-08-26

	* src/context.c:
	* src/context_priv.c:
	* src/context_priv.h: libotr was exporting exactly two functions
	without the otrl_ prefix: context_priv_new and
	context_priv_force_finished.  Change the names of these
	functions to start with otrl_.  Thanks to David Goulet
	<dgoulet@ev0ke.net> for noticing it.

	* Protocol-v3.html: Document the v3 whitespace tag, and better
	document the extra symmetric key.  Thanks to Kjell Braden
	<kb@pentabarf.de> for noticing the omission.

2012-08-25

	* src/sm.c:
	* src/context.c:
	* src/auth.c:
	* src/message.c: If OTRL_DEBUGGING is non-zero, then a message
	containing a special debug string ("?OTR!") will cause debug
	info to be printed to stderr.  (This #define should *not* be set
	in release code.)

	* src/auth.c:
	* src/auth.h:
	* src/message.c: Correct the logic for handling incoming COMMIT
	messages when we've recently sent our own COMMIT message.

	* src/message.c: Don't update the recent_sent_child field to
	point to the master context just becuase we sent a version 3
	COMMIT message (which has no destination instance).

2012-08-24

	* README:
	* configure.ac: Prepare for release 4.0.0

2012-08-24

	* src/message.c: Consider copying the master auth context to the
	child, even if the child is already in ENCRYPTED, because we
	might be trying to refresh a private conversation.

2012-08-22

	* configure.ac: Use gcc and ld hardening flags, where possible.
	* configure.ac:
	* src/auth.c:
	* src/dh.c:
	* src/mem.c:
	* src/privkey.c:
	* src/proto.c:
	* src/sm.c:
	* toolkit/sesskey.c: Build cleanly with -Wall -Wextra
	-Wformat-security -Wno-unused-parameter

2012-08-17

	* src/message.c: Don't call memchr(foo,'\0',-1) even if it has
	no ill effects.  Thanks to George Kadianakis
	<desnacked@riseup.net> for the report.

2012-07-20

	* src/message.c, src/instag.c, toolkit/parse.c, src/sm.c,
	src/proto.c, src/privkey.c, src/auth.c, src/context.[ch]:
	Fix some memory leaks, some NULL pointer handling, and
	compilation warnings.  Thanks to Paul Wouters
	<pwouters@redhat.com> for the report.

	* src/message.c: Better handling of OTRv3 fragments.

2012-07-19

	* src/b64.[ch], src/proto.c, toolkit/parse.c: Clean up the
	previous b64 patch and apply it to all places where
	otrl_base64_decode() is called.

2012-07-17

	* src/b64.c: Use ceil instead of floor to compute the size
	of the data buffer.  This prevents a one-byte heap buffer
	overflow.  Thanks to Justin Ferguson <jnferguson@gmail.com>
	for the report.

2012-06-21

	* src/context.c: A couple bug fixes.
	* Release 4.0.0-beta2

2009-04-28:

	* src/auth.c: pubkey_type should be shifted by 8, not 16.  It
	doesn't matter right now, because it's always 0, but still.

	that can be used for things like file transfers.

	* message.h:
	* message.c: Applications now use the handle_smp_event callback
	to handle SMP events, rather than having to hardcode part of the
	SMP state machine themselves.

	session id in the middle of the conversation, the value
	displayed should be the one calculated at the time the private
	connection was established (the last Key Exchange Message that
	caused a rekeying), _not_ the DH secure id calculated from DH
	keys in more recent Data Messages.

	* libotr.m4: Have the version check require an exact match on
	the major version, since, for example, source that expects
	libotr 2.0.0 won't work with libotr 3.0.0.

	* libotr.m4: Add #include <stdlib.h> to the version test so that
	it compiles cleanly with -Wall -Werror.

	* src/proto.c:
	* src/dh.h:
	* src/dh.c:
	* src/context.h:
	* src/context.c: Save the secure session id so that it can be
	displayed to the user upon request, instead of only when the
	private session is initially set up.

	* src/privkey.c:
	* src/context.h:
	* src/context.c: Allow the app to set a "trust level" for
	fingerprints.  This is an arbitrary string, intended to indicate
	whether (or possibly by what means) the user has verified that
	this fingerprint is accurate.

	* src/context.h:
	* src/context.c: Allow the app to set an arbitrary binary
	"preshared secret" for the ConnContext.  This is currently
	unused, but in the future it would allow for users to exchange a
	secret _before_ they generate their fingerprints.  [But the
	protocol would have to be extended to support this.]

	* src/message.h:
	* src/message.c: Remove the "confirm_fingerprint" callback
	which requires the user to acknowledge the new fingerprint
	before it can be used.  Replace it with a "new_fingerprint"
	callback which merely informs the user that a new fingerprint
	has been received.

	* libotr.m4: Fixed a bug which made configure fail to find the
	libotr header files if they weren't in the standard place.

2005-05-09

	* src/message.c (otrl_message_sending): Don't show the user the
	"the last message was resent" notice if the message has never
	actually been sent before.

2005-02-09

	* src/proto.c (otrl_proto_create_data): Copy the msg before
	using since, since it may be an alias for context->lastmessage,
