Ok sorry for the delay, I have some questions. Can you provide links
to the code commits fixing these issues/give some details on them?
Also I assume the Cryptocat 2.1 release fixes the decryptocat issue
correct?
==============
https://github.com/cryptocat/cryptocat/blob/master/CHANGELOG.md
Cryptocat 2.1
Jun. 7 2013
Security enhancements and bug fixes. Updating is recommended.
Cryptocat 2.0.42
Apr. 19 2013
Fixed a bug found in the encryption libraries that could partially
weaken the security of multiparty Cryptocat messages.
Cryptocat 2.0.22
Nov. 7 2012
This version pushes many important security fixes, detailed here on
the Cryptocat Development Blog:
https://blog.crypto.cat/2012/11/security-update-our-first-full-audit/
Cryptocat 2.0.19
Nov. 1 2012
Minor security fixes.
==============
Second set of questions:
Then in http://tobtu.com/decryptocat.php
A number of other issues are mentioned, but I can't easily match them
up to the changelog:
Date introduced Days in Git Difficulty rating
Jul 9, 2011 58 Passwords so probably broken
Sep 5, 2011 6 *** Medium
Sep 11, 2011 36 **** Hard
Oct 15, 2011 2 ***** "Impossible"
Oct 17, 2011 12 *** Medium
Oct 29, 2011 191 ** Easy
May 7, 2012 347 * Encraption
Apr 19, 2013 45 *** Medium
Jun 3, 2013 30+ ***** "Impossible"
Can you provide links to the commits for these issues?
It looks like we need between 4 and 10+ CVEs in total.
