USN-1372-1: Puppet vulnerabilities

23 February 2012

Puppet could be made to overwrite files and run programs with administrator privileges.



  • puppet - Centralized configuration management


It was discovered that Puppet did not drop privileges when executing
commands as different users. If an attacker had control of the execution
manifests or the executed command, this could be used to execute code with
elevated group permissions (typically root). (CVE-2012-1053)

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 and escalate privileges. (CVE-2012-1054)

Update instructions

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

Ubuntu 11.10
Ubuntu 11.04
Ubuntu 10.10
Ubuntu 10.04

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