Details
It was discovered that Puppet incorrectly handled certain HTTP GET
requests. An attacker could use this flaw with a valid client certificate
to retrieve arbitrary files from the Puppet primary server.
(CVE-2012-3864)
It was discovered that Puppet incorrectly handled Delete requests. If a
Puppet primary server were reconfigured to allow the "Delete" method, an
attacker on an authenticated host could use this flaw to delete arbitrary
files from the Puppet server, leading to a denial of service.
(CVE-2012-3865)
It was discovered that Puppet incorrectly set file permissions on the
last_run_report.yaml file. An attacker could use this flaw to access
sensitive information. This issue only affected Ubuntu 11.10 and Ubuntu
12.04 LTS. (CVE-2012-3866)
It was discovered that Puppet incorrectly handled agent certificate names.
An attacker could use this flaw to create a specially crafted certificate
and trick an administrator into signing a certificate that can then be used
to machine-in-the-middle agent nodes. (CVE-2012-3867)
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.04
