Several security issues were fixed in Puppet.

Releases

Packages

  • 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
Ubuntu 11.10
Ubuntu 11.04
Ubuntu 10.04

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