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" |
| 74 |
|
