Untrusted search path vulnerability in Puppet Enterprise 2.8 before 2.8.7, Puppet before 2.7.26 and 3.x before 3.6.2, Facter 1.6.x and 2.x before 2.0.2, Hiera before 1.3.4, and Mcollective before 2.5.2, when running with Ruby 1.9.1 or earlier, allows local users to gain privileges via a Trojan horse file in the current working directory, as demonstrated using (1) rubygems/defaults/operating_system.rb, (2) Win32API.rb, (3) Win32API.so, (4) safe_yaml.rb, (5) safe_yaml/deep.rb, or (6) safe_yaml/deep.so; or (7) operatingsystem.rb, (8) operatingsystem.so, (9) osfamily.rb, or (10) osfamily.so in puppet/confine.

Multiple cross-site request forgery (CSRF) vulnerabilities in Puppet Enterprise (PE) before 3.0.1 allow remote attackers to hijack the authentication of users for requests that deleting a (1) report, (2) group, or (3) class or possibly have other unspecified impact.

telnet.rb in Puppet 2.7.x before 2.7.13 and Puppet Enterprise (PE) 1.2.x, 2.0.x, and 2.5.x before 2.5.1 allows local users to overwrite arbitrary files via a symlink attack on the NET::Telnet connection log (/tmp/out.log).

Puppet 2.6.x before 2.6.15 and 2.7.x before 2.7.13, and Puppet Enterprise (PE) Users 1.0, 1.1, 1.2.x, 2.0.x, and 2.5.x before 2.5.1 allows remote authenticated users with an authorized SSL key and certain permissions on the puppet master to read arbitrary files via a symlink attack in conjunction with a crafted REST request for a file in a filebucket.

Unspecified vulnerability in Puppet 2.6.x before 2.6.15 and 2.7.x before 2.7.13, and Puppet Enterprise (PE) Users 1.0, 1.1, 1.2.x, 2.0.x, and 2.5.x before 2.5.1 allows remote authenticated users with agent SSL keys to (1) cause a denial of service (memory consumption) via a REST request to a stream that triggers a thread block, as demonstrated using CVE-2012-1986 and /dev/random; or (2) cause a denial of service (filesystem consumption) via crafted REST requests that use "a marshaled form of a Puppet::FileBucket::File object" to write to arbitrary file locations.

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.

Puppet 2.6.x before 2.6.15 and 2.7.x before 2.7.13, and Puppet Enterprise (PE) Users 1.0, 1.1, 1.2.x, 2.0.x, and 2.5.x before 2.5.1 uses predictable file names when installing Mac OS X packages from a remote source, which allows local users to overwrite arbitrary files or install arbitrary packages via a symlink attack on a temporary file in /tmp.

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.
