Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Two vulnerabilities in Imlib 2 may allow for the execution of arbitrary |
| 19 |
code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Imlib 2 is an advanced replacement library for libraries like libXpm. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|

Package / Vulnerable / Unaffected |

| 32 |
1 media-libs/imlib2 < 1.4.0-r1 >= 1.4.0-r1 |
| 33 |
|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Stefan Cornelius (Secunia Research) reported two boundary errors in |
| 38 |
Imlib2: |
| 39 |
|
| 40 |
* One of them within the load() function in the file |
| 41 |
src/modules/loaders/loader_pnm.c when processing the header of a PNM |
| 42 |
image file, possibly leading to a stack-based buffer overflow. |
| 43 |
|
| 44 |
* The second one within the load() function in the file |
| 45 |
src/modules/loader_xpm.c when processing an XPM image file, possibly |
| 46 |
leading to a stack-based buffer overflow. |
| 47 |
|
| 48 |
Impact |
| 49 |
====== |
| 50 |
|
| 51 |
A remote attacker could entice a user to open a specially crafted PNM |
| 52 |
or XPM image, possibly resulting in the execution of arbitrary code |
| 53 |
with the rights of the user running the application using Imlib 2. |
| 54 |
|
| 55 |
Workaround |
| 56 |
========== |
| 57 |
|
| 58 |
There is no known workaround at this time. |
| 59 |
|
| 60 |
Resolution |
| 61 |
========== |
| 62 |
|
| 63 |
All Imlib 2 users should upgrade to the latest version: |
| 64 |
|
| 65 |
# emerge --sync |
| 66 |
# emerge --ask --oneshot --verbose ">=media-libs/imlib2-1.4.0-r1" |
| 67 |
|
