Description Kurt Seifried 2012-07-11 05:02:38 UTC

From puppet labs: CVE-2012-3865 (Arbitrary file delete/D.O.S on Puppet Master)

A bug in Puppet 2.6.16 and 2.7.17 allows authenticated clients to delete 
arbitrary files on the puppet master.

Given a Puppet master with the “Delete” method allowed in auth.conf for an 
authenticated host, an attacker on that host can send a specially crafted 
Delete request that can cause an arbitrary file deletion on the Puppet master,
 potentially causing a denial of service attack. Note that this vulnerability 
does *not* exist in Puppet as configured by default; auth.conf must first be 
edited to enable deletion.

Resolved in Puppet 2.6.17, 2.7.18
