Description Sam Fowler 2018-02-07 07:34:50 UTC

In puppet before versions 4.10.10 and 5.3.4, when unpacking tarballs with minitar in lib/puppet/module_tool/tar/mini.rb, files are unpacked with the same permissions as in the tarball allowing for files with unsafe permissions.

Created puppet tracking bugs for this issue:

Affects: fedora-all [bug 1542852]

Comment 3 Kurt Seifried 2018-02-09 16:10:30 UTC

Please note that Puppet 3.x has mini.rb with the exact same code as 4.x, so it appears to be vulnerable, additionally the patch at https://github.com/puppetlabs/puppet/commit/17d9e02da3882e44c1876e2805cf9708481715ee should fix it.
