./chat/libotr, Library for Off-The-Record encrypted messaging

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 4.1.1, Package name: libotr-4.1.1, Maintainer: nathanw

This is the portable OTR Messaging Library, as well as the toolkit to
help you forge messages.

Off-the-Record (OTR) Messaging allows you to have private
conversations over instant messaging by providing:

No one else can read your instant messages.
You are assured the correspondent is who you think it is.
The messages you send do not have digital signatures that are
checkable by a third party. Anyone can forge messages after a
conversation to make them look like they came from you. However,
during a conversation, your correspondent is assured the messages
he sees are authentic and unmodified.
Perfect forward secrecy
If you lose control of your private keys, no previous conversation
is compromised.

Log message:
Update to 4.1.1.

This is a security release addressing CVE-2016-2851.

- Fix an integer overflow bug that can cause a heap buffer overflow (and
  from there remote code execution) on 64-bit platforms
- Fix possible free() of an uninitialized pointer
- Be stricter about parsing v3 fragments
- Add a testsuite ("make check" to run it), but only on Linux for now,
  since it uses Linux-specific features such as epoll
- Fix a memory leak when reading a malformed instance tag file
- Protocol documentation clarifications

Add SHA512 digests for distfiles for chat category

Problems found with existing distfiles:
No changes made to these /distinfo files.

Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden).  All existing
SHA1 digests retained for now as an audit trail.

   2012-09-06 02:23:19 by Greg Troxel | Files touched by this commit (4) | Package updated
Log message:
Update to 4.0.0.

Note that while the protocol is compatible, the API is not, and hence
there will be a pidgin-otr update within minutes.

There is an apparent gcc 4.1.3 -O2/SSP bug, which is avoided by
disabling SSP in libotr (which libotr finds and turns on).  This is
temporary pending more fine-grained control and/or a fix.

Update to libotr 4.0.0.  Note that libotr 4.x is API-incompatible with
libotr 3.x; upstream thinks this is ok, so pkgsrc won't try to work
around it.

24 Aug 2012:
- Release 4.0.0
- Support v3 of the OTR protocol
- The main new feature: sensibly handle the case where a user is logged
  in multiple times to the same IM account
- API changes:
  - instance tags, to support multiple simultaneous logins
  - support for asynchronous private key generation
  - the ability to provide an "extra" symmetric key to applications
    (with forward secrecy)
  - applications can supply a formation conversion callback if they do
    not natively use XHTML-style UTF8 markup
  - error messages formerly provided by libotr are now handled using
    callbacks to the application, for better i18n support
  - otrl_message_sending now handles message fragmentation internally
