Synopsis |
| 17 |
======== |
| 18 |
|
| 19 |
The foomatic-rip filter in foomatic-filters contains a vulnerability |
| 20 |
which may allow arbitrary command execution on the print server. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
Foomatic is a system for connecting printer drivers with spooler |
| 26 |
systems such as CUPS and LPD. The foomatic-filters package contains |
| 27 |
wrapper scripts which are designed to be used with Foomatic. |
| 28 |

Description |
| 42 |
=========== |
| 43 |
|
| 44 |
There is a vulnerability in the foomatic-filters package. This |
| 45 |
vulnerability is due to insufficient checking of command-line |
| 46 |
parameters and environment variables in the foomatic-rip filter. |
| 47 |
|
| 48 |
Impact |
| 49 |
====== |
| 50 |
|
| 51 |
This vulnerability may allow both local and remote attackers to execute |
| 52 |
arbitrary commands on the print server with the permissions of the |
| 53 |
spooler (oftentimes the "lp" user). |
| 54 |
|
| 55 |
Workaround |
| 56 |
========== |
| 57 |
|
| 58 |
There is no known workaround at this time. |
| 59 |
|
| 60 |
Resolution |
| 61 |
========== |
| 62 |
|
| 63 |
All foomatic users should upgrade to the latest version: |
| 64 |
|
| 65 |
# emerge sync |
| 66 |
|
| 67 |
# emerge -pv ">=net-print/foomatic-3.0.2" |
| 68 |
# emerge ">=net-print/foomatic-3.0.2" |
| 69 |
|
| 70 |
PLEASE NOTE: You should update foomatic, instead of foomatic-filters. |
| 71 |
This will help to ensure that all other foomatic components remain |
| 72 |
functional. |
