CVE-2017-10689 puppet: Unpacking of tarballs in tar/mini.rb can create files with insecure permissions
Last modified: 2018-10-16 11:20:37 EDT
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. Upstream Advisory: https://puppet.com/security/cve/CVE-2017-10689 Upstream Issue: https://tickets.puppetlabs.com/browse/PUP-7866 Upstream Commit: https://github.com/puppetlabs/puppet/commit/17d9e02da3882e44c1876e2805cf9708481715ee
Created puppet tracking bugs for this issue: Affects: fedora-all [bug 1542852]
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.
