Synopsis |
| 16 |
======== |
| 17 |

| 19 |
to execute arbitrary code. |

|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |

Description |
| 37 |
=========== |
| 38 |
|
| 39 |
It was discovered that LittleCMS (aka Little Color Management System) |
| 40 |
had an integer overflow in the AllocateDataSet function in cmscgats.c. |
| 41 |
|
| 42 |
Impact |
| 43 |
====== |
| 44 |
|
| 45 |
A remote attacker could entice a user or automated system to open a |
| 46 |
specially crafted file containing malicious color data, possibly |
| 47 |
resulting in execution of arbitrary code with the privileges of the |
| 48 |
process or a Denial of Service condition. |
| 49 |
|
| 50 |
Workaround |
| 51 |
========== |
| 52 |
|
| 53 |
There is no known workaround at this time. |
| 54 |
|
| 55 |
Resolution |
| 56 |
========== |
| 57 |
|
| 58 |
All LittleCMS users should upgrade to the latest version: |
| 59 |
|
| 60 |
# emerge --sync |
| 61 |
# emerge --ask --oneshot --verbose ">=media-libs/lcms-2.10" |
