Description Kurt Seifried 2012-04-05 04:02:18 UTC

From Matthaus Litteken <matthaus>:

CVE-2012-1987 (Moderate) [#13552,#13553] - Filebucket denial of service
By constructing a marshaled form of a Puppet::FileBucket::File object 
a user can cause it it to be written to any place on the disk of the 
puppet master. This could be used for a denial of service attach 
against the puppet master if an attacker fills a filesystem that can 
cause systems to stop working. In order to do this the attacker needs 
no access to the puppet master system, but does need access to agent 
SSL keys.
