Synopsis |
16 |
======== |
17 |
|
18 |
Multiple errors in LittleCMS allow for attacks including the remote |
19 |
execution of arbitrary code. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
LittleCMS, or short lcms, is a color management system for working with |
25 |
ICC profiles. It is used by many applications including GIMP and |
26 |
Firefox. |
27 |
|
28 |
Affected packages |

Description |
37 |
=========== |
38 |
|
39 |
RedHat reported a null-pointer dereference flaw while processing |
40 |
monochrome ICC profiles (CVE-2009-0793). |
41 |
|
42 |
Chris Evans of Google discovered the following vulnerabilities: |
43 |
|
44 |
* LittleCMS contains severe memory leaks (CVE-2009-0581). |
45 |
|
46 |
* LittleCMS is prone to multiple integer overflows, leading to a |
47 |
heap-based buffer overflow (CVE-2009-0723). |
48 |
|
49 |
* The ReadSetOfCurves() function is vulnerable to stack-based buffer |
50 |
overflows when called from code paths without a bounds check on |
51 |
channel counts (CVE-2009-0733). |
52 |
|
53 |
Impact |
54 |
====== |
55 |
|
56 |
A remote attacker could entice a user or automated system to open a |
57 |
specially crafted file containing a malicious ICC profile, possibly |
58 |
resulting in the execution of arbitrary code with the privileges of the |
59 |
user running the application or memory exhaustion, leading to a Denial |
60 |
of Service condition. |
61 |
|
62 |
Workaround |
63 |
========== |
64 |
|
65 |
There is no known workaround at this time. |
66 |
|
67 |
Resolution |
68 |
========== |
69 |
|
70 |
All LittleCMS users should upgrade to the latest version: |
71 |
|
72 |
# emerge --sync |
73 |
# emerge --ask --oneshot --verbose ">=media-libs/lcms-1.18-r1" |
