It looks like the bug report has been opened after we requested support to Canonical (the cn of that cert is ours). I'm kindly asking if there's any eta for the fix, even in major version 3.x. We can plan an upgrade to 3.x but we'd like to be sure of the version containing the fix. Thanks. ---------------------------------------- Bug #15561: Fix for CVE-2012-3867 is too restrictive https://projects.puppetlabs.com/issues/15561#change-83401 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.
