Synopsis |
16 |
======== |
17 |
|
18 |
Multiple errors in CUPS might allow for the remote execution of |
19 |
arbitrary code or DNS rebinding attacks. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
CUPS, the Common Unix Printing System, is a full-featured print server. |
25 |
|
26 |
Affected packages |
27 |
================= |
28 |
|
29 |
------------------------------------------------------------------- |
30 |
Package / Vulnerable / Unaffected |

Description |
35 |
=========== |
36 |
|
37 |
The following issues were reported in CUPS: |
38 |
|
39 |
* iDefense reported an integer overflow in the _cupsImageReadTIFF() |
40 |
function in the "imagetops" filter, leading to a heap-based buffer |
41 |
overflow (CVE-2009-0163). |
42 |
|
43 |
* Aaron Siegel of Apple Product Security reported that the CUPS web |
44 |
interface does not verify the content of the "Host" HTTP header |
45 |
properly (CVE-2009-0164). |
46 |
|
47 |
* Braden Thomas and Drew Yao of Apple Product Security reported that |
48 |
CUPS is vulnerable to CVE-2009-0146, CVE-2009-0147 and CVE-2009-0166, |
49 |
found earlier in xpdf and poppler. |
50 |
|
51 |
Impact |
52 |
====== |
53 |
|
54 |
A remote attacker might send or entice a user to send a specially |
55 |
crafted print job to CUPS, possibly resulting in the execution of |
56 |
arbitrary code with the privileges of the configured CUPS user -- by |
57 |
default this is "lp", or a Denial of Service. Furthermore, the web |
58 |
interface could be used to conduct DNS rebinding attacks. |
59 |
|
60 |
Workaround |
61 |
========== |
62 |
|
63 |
There is no known workaround at this time. |
64 |
|
65 |
Resolution |
66 |
========== |
67 |
|
68 |
All CUPS users should upgrade to the latest version: |
69 |
|
70 |
# emerge --sync |
71 |
# emerge --ask --oneshot --verbose ">=net-print/cups-1.3.10" |
72 |
