CVE-2012-3867 Information

Description

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.
