Ubuntu 10.04 LTS / 11.04 / 11.10 / 12.04 LTS : puppet vulnerabilities (USN-1506-1)

medium Nessus Plugin ID 59965

Language:

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected puppet-common package.
