DESCRIPTION:
Multiple security issues and two vulnerabilities have been reported
in Puppet, which can be exploited by malicious, local users to
disclose potentially sensitive information and perform certain
actions with escalated privileges and by malicious users to cause a
DoS (Denial of Service).

1) An error due to the application creating a temporary file in an
insecure manner when installing Mac OS X packages from remote sources
can be exploited to e.g. overwrite arbitrary files or install an
arbitrary package via symlink attacks.

2) An error when handling REST requests for a file from a remote
filebucket can be exploited to change the defined location for
filebucket storage and thus read files from the user account running
the puppet master via symlink attacks.

Successful exploitation of this vulnerability requires an authorized
SSL key.

3) An error when handling a marshalled Puppet::FileBucket::File
object can be exploited to exhaust system resources via specially
crafted REST requests.

4) An error when handling file bucket requests can be exploited to
execute certain shell commands by requesting an existing file
containing executable commands within its path.

Successful exploitation of vulnerability #3 and #4 requires agent SSL
keys.

5) An error due to the application creating an output log for
NET::Telnet connections in an insecure manner can be exploited to
e.g. overwrite arbitrary files via symlink attacks.

Please see the vendor's advisories for a list of affected versions.

SOLUTION:
Update to a fixed version or apply hotfixes (please see the vendor's
advisories for details).
