Puppet agent 5.5.3

Released June 13, 2018.

This release of Puppet agent resolves a critical Windows installer bug.

Component updates

There are no component updates in this Puppet agent release.

Bug fixes

• The previous version of the Windows Puppet agent installer had an internal MSI property resolution issue that could be triggered when requesting that msiexec install the same version of the Puppet agent package that was already installed on the node. In those rare instances, and when combined with the permission resetting code introduced in PA-2019 as a response to CVE-2018-6513, the Puppet agent package could execute takeown.exe and icacls.exe against the filesystem root (C:\), resulting in incorrectly rewritten permissions across the filesystem.

  Using the Chocolatey package provider to perform an in-place upgrade of the Puppet package during a Puppet run, which is the workflow used by Foreman, most commonly triggered this behavior.

  Puppet agent 5.5.3 resolves both of these problems by implementing a workaround of the MSI property resolution issue and making the PA-2019 permission resetting code more defensive. (PA-2075)

• In Puppet agent 5.5.2, Puppet’s systemd services were not always enabled as expected on Debian and derivative operating systems, such as within the debian-installer chroot. This could lead to Puppet services being disabled after an automated deployment of agent 5.5.2 on these operating systems. Puppet agent 5.5.3 fixes this regression. (PA-2072)

Puppet agent 5.5.2

Released June 7, 2018.

This release of Puppet Platform contains several Puppet and Facter security and bug fixes.

Component updates

This release includes component updates to Puppet 5.5.2, Facter 3.11.2, MCollective 2.12.2, and pxp-agent 1.9.2.

Known issues

• Due to an issue with the Windows installer, Puppet agent 5.5.2 can inadvertently change permissions on files across a Windows node’s filesystem when re-installed or in certain rare installation scenarios. This can cause serious issues on those nodes. The Puppet agent 5.5.2 installer binaries for Windows have been removed from our downloads as well as the Chocolatey community feed, and they should not be installed if downloaded or installed on their own or as part of Puppet Enterprise (PE) 2018.1.1. (PA-2075)

Bug fixes

• Previous versions of Puppet on Ruby 2.0 or newer would close and reopen HTTP connection that were idle for more than 2 seconds, causing increased load on Puppet masters. This version of Puppet ensures that the agent uses the http_keepalive_timeout setting when determining when to close idle connections. (PUP-8663)

• When installing or updating puppet-agent 5.5.2, it updates the MANPATH environment variable so that Puppet’s man pages are available. (PA-1847)

Security updates

• On Windows, Puppet no longer includes /opt/puppetlabs/puppet/modules in its default basemodulepath, because unprivileged users could create a C:\opt directory and escalate privileges. (PUP-8707)

• This version of Puppet agent restricts permissions to some directories within C:\ProgramData\PuppetLabs so that only LocalSystem and members of the local Administrators group have access. (PA-2019)

Puppet agent 5.5.1

Released April 17, 2018.

This release of Puppet Platform contains several new features and bug fixes.

Component updates

This release includes component updates to Puppet 5.5.1, Facter 3.11.1, Hiera 3.4.3, MCollective 2.12.1, pxp-agent 1.9.1, and LTH 1.4.1.

Platform updates

This release removes packages for Fedora 25, macOS 10.10 and 10.11, Scientific Linux 5, and Windows Vista.

Security updates

• Updates curl to version 7.59.0. (PA-1913)

Bug fixes

• MCollective now relies only on its internal log rotation rather than also using logrotate config. This prevents conflicting rotation and simplifies the config. (PA-1908)

• Log rotation under systemd correctly signals pxp-agent to re-open the log file. (PCP-834)

New features

• puppet-agent 5.5.1 and above now ships the hiera-eyaml 2.1.0, highline 1.6.21, and trollop 2.1.2 Ruby gems in the shared gem directory. (PA-1925)
