Amazon Linux 1 Security Advisory: ALAS-2012-53
Advisory Release Date: 2012-03-15 19:11 Pacific
Advisory Updated Date: 2014-09-14 15:40 Pacific
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, when managing a user login file with the k5login resource type, allows local users to gain privileges via a symlink attack on .k5login.
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.
Affected Packages:
puppet
Issue Correction:
Run yum update puppet to update your system.
