==========================================================================
Ubuntu Security Notice USN-1506-1
July 12, 2012

puppet vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in Puppet.

Software Description:
- puppet: Centralized configuration management

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 master. (CVE-2012-3864)

It was discovered that Puppet incorrectly handled Delete requests. If a
Puppet master 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 man-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 LTS:
  puppet-common                   2.7.11-1ubuntu2.1

Ubuntu 11.10:
  puppet-common                   2.7.1-1ubuntu3.7

Ubuntu 11.04:
  puppet-common                   2.6.4-2ubuntu2.10

Ubuntu 10.04 LTS:
  puppet-common                   0.25.4-2ubuntu6.8

In general, a standard system update will make all the necessary changes.
