Test ID:1.3.6.1.4.1.25623.1.0.70954
Category:Ubuntu Local Security Checks
Title:Ubuntu USN-1223-2 (puppet-common)
Summary:Ubuntu USN-1223-2 (puppet-common)
Description:The remote host is missing an update to puppet-common
announced via advisory USN-1223-2.

Details:

USN-1223-1 fixed vulnerabilities in Puppet. A regression was found on
Ubuntu 10.04 LTS that caused permission denied errors when managing SSH
authorized_keys files with Puppet. This update fixes the problem.

We apologize for the inconvenience.

Original advisory details:

It was discovered that Puppet unsafely opened files when the k5login type
is used to manage files. A local attacker could exploit this to overwrite
arbitrary files which could be used to escalate privileges. (CVE-2011-3869)

Ricky Zhou discovered that Puppet did not drop privileges when creating
SSH authorized_keys files. A local attacker could exploit this to overwrite
arbitrary files as root. (CVE-2011-3870)

It was discovered that Puppet used a predictable filename when using the
--edit resource. A local attacker could exploit this to edit arbitrary
files or run arbitrary code as the user invoking the program, typically
root. (CVE-2011-3871)

Solution:
The problem can be corrected by updating your system to the following
package versions:

Ubuntu 10.04 LTS:
puppet-common 0.25.4-2ubuntu6.4
