Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2012-3867 medium priority: Ubuntu including 1 source packages (puppet), 6 status rows across 6 suites (hardy, lucid, natty, oneiric, precise, upstream): released 5, ignored 1.
lib/puppet/ssl/certificate_authority.rb in Puppet before 2.6.17 and 2.7.x before 2.7.18, and Puppet Enterprise before 2.5.2, does not properly restrict the characters in the Common Name field of a Certificate Signing Request (CSR), which makes it easier for user-assisted remote attackers to trick administrators into signing a crafted agent certificate via ANSI control sequences.
