CVE-2012-1053

Status Candidate

Overview

The change_user method in the SUIDManager (lib/puppet/util/suidmanager.rb) in Puppet 2.6.x before 2.6.14 and 2.7.x before 2.7.11, and Puppet Enterprise (PE) Users 1.0, 1.1, 1.2.x, 2.0.x before 2.0.3 does not properly manage group privileges, which allows local users to gain privileges via vectors related to (1) the change_user not dropping supplementary groups in certain conditions, (2) changes to the eguid without associated changes to the egid, or (3) the addition of the real gid to supplementary groups.

Ubuntu Security Notice USN-1372-1
Posted Feb 24, 2012
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 1372-1 - 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). 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. Various other issues were also addressed.
