Unfortunately this change does not sufficiently address the root cause of the problem, and as a result risks regression of CVE-2012-3867. Please see the comments I posted on Github for more information and next steps to proceed. ---------------------------------------- Bug #15561: Fix for CVE-2012-3867 is too restrictive https://projects.puppetlabs.com/issues/15561#change-83690 Author: Dustin Mitchell Status: Accepted Priority: Urgent Assignee: Category: SSL Target version: Affected Puppet version: 2.7.18 Keywords: certificate Branch: https://github.com/puppetlabs/puppet/pull/1101 The fix for CVE-2012-3867 involves checking certificate subjects for "weird" characters. From my read of the CVE entry, this is to filter out characters that would cause the name to display in a manner visually indistinguishable from a valid hostname. However, the check is too restrictive: Could not retrieve catalog from remote server: Certname "puppetagain base ca/emailaddress=rele...@mozilla.com/ou=release engineering/o=mozilla, inc." must not contain unprintable or non-ASCII characters In particular, / is a very common character in subjects, and should be allowed. Puppet is seeing this subject on my base CA - I'm using certificate chaining. The fix is one character, so I haven't included a patch, but I'm happy to make a pull req if necessary. Another fix would be to only verify certificate subjects for the leaf certificate, and not any of the certs in its signing chain, but that seems less secure. It's also worth noting that the regex is overly broad, since it downcases the string, then accepts A-Z among other characters. -- You have received this notification because you have either subscribed to it, or are involved in it.
