Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple vulnerabilities have been found in Puppet, the worst of which |
| 19 |
could lead to execution of arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Puppet is a system configuration management tool written in Ruby. |
| 25 |
|
| 26 |
Affected packages |

Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Multiple vulnerabilities have been found in Puppet: |
| 38 |
|
| 39 |
* Puppet uses predictable file names for temporary files |
| 40 |
(CVE-2012-1906). |
| 41 |
* REST requests for a file in a remote filebucket are not handled |
| 42 |
properly by overriding filebucket storage locations (CVE-2012-1986). |
| 43 |
* REST requests for a file in a remote filebucket are not handled |
| 44 |
properly by reading streams or writing files on the Puppet master's |
| 45 |
file system (CVE-2012-1987). |
| 46 |
* File name paths are not properly sanitized from bucket requests |
| 47 |
(CVE-2012-1988). |
| 48 |
* The Telnet utility in Puppet does not handle temporary files securely |
| 49 |
(CVE-2012-1989). |

|
| 51 |
Impact |
| 52 |
====== |
| 53 |
|
| 54 |
A local attacker with access to agent SSL keys could possibly execute |
| 55 |
arbitrary code with the privileges of the process, cause a Denial of |
| 56 |
Service condition, or perform symlink attacks to overwrite or read |
| 57 |
arbitrary files on the Puppet master. |
| 58 |
|
| 59 |
Workaround |
| 60 |
========== |
| 61 |
|
| 62 |
There is no known workaround at this time. |
| 63 |
|
| 64 |
Resolution |
| 65 |
========== |
| 66 |
|
| 67 |
All Puppet users should upgrade to the latest version: |
| 68 |
|
| 69 |
# emerge --sync |
| 70 |
# emerge --ask --oneshot --verbose ">=app-admin/puppet-2.7.13" |
| 71 |
|
