Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple overflows have been found in the imlib library image decoding |
| 19 |
routines, potentially allowing execution of arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
imlib is an advanced replacement library for image manipulation |
| 25 |
libraries like libXpm. It is called by numerous programs, including |
| 26 |
gkrellm and several window managers, to help in displaying images. |
| 27 |

Description |
| 37 |
=========== |
| 38 |
|
| 39 |
Pavel Kankovsky discovered that several overflows found in the libXpm |
| 40 |
library (see GLSA 200409-34) also applied to imlib. He also fixed a |
| 41 |
number of other potential flaws. |
| 42 |
|
| 43 |
Impact |
| 44 |
====== |
| 45 |
|
| 46 |
A remote attacker could entice a user to view a carefully-crafted image |
| 47 |
file, which would potentially lead to execution of arbitrary code with |
| 48 |
the rights of the user viewing the image. This affects any program that |
| 49 |
makes use of the imlib library. |
| 50 |
|
| 51 |
Workaround |
| 52 |
========== |
| 53 |
|
| 54 |
There is no known workaround at this time. |
| 55 |
|
| 56 |
Resolution |
| 57 |
========== |
| 58 |
|
| 59 |
All imlib users should upgrade to the latest version: |
| 60 |
|
| 61 |
# emerge --sync |
| 62 |
# emerge --ask --oneshot --verbose ">=media-libs/imlib-1.9.14-r3" |
| 63 |
|
