Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Two boundary errors have been identified in SDL_image allowing for the |
| 19 |
remote execution of arbitrary code or the crash of the application |
| 20 |
using the library. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
SDL_image is an image file library that loads images as SDL surfaces, |
| 26 |
and supports various formats like BMP, GIF, JPEG, LBM, PCX, PNG, PNM, |
| 27 |
TGA, TIFF, XCF, XPM, and XV. |
| 28 |
|
| 29 |
Affected packages |
| 30 |
================= |
| 31 |
|
| 32 |
------------------------------------------------------------------- |
| 33 |
Package / Vulnerable / Unaffected |
| 34 |
------------------------------------------------------------------- |
| 35 |
1 media-libs/sdl-image < 1.2.6-r1 >= 1.2.6-r1 |
| 36 |
|
| 37 |
Description |
| 38 |
=========== |
| 39 |
|
| 40 |
The LWZReadByte() function in file IMG_gif.c and the IMG_LoadLBM_RW() |
| 41 |
function in file IMG_lbm.c each contain a boundary error that can be |
| 42 |
triggered to cause a static buffer overflow and a heap-based buffer |
| 43 |
overflow. The first boundary error comes from some old vulnerable GD |
| 44 |
PHP code (CVE-2006-4484). |
| 45 |
|
| 46 |
Impact |
| 47 |
====== |
| 48 |
|
| 49 |
A remote attacker can make an application using the SDL_image library |
| 50 |
to process a specially crafted GIF file or IFF ILBM file that will |
| 51 |
trigger a buffer overflow, resulting in the execution of arbitrary code |
| 52 |
with the permissions of the application or the application crash. |
| 53 |
|
| 54 |
Workaround |
| 55 |
========== |
| 56 |
|
| 57 |
There is no known workaround at this time. |
| 58 |
|
| 59 |
Resolution |
| 60 |
========== |
| 61 |
|
| 62 |
All SDL_image users should upgrade to the latest version: |
| 63 |
|
| 64 |
# emerge --sync |
| 65 |
# emerge --ask --oneshot --verbose ">=media-libs/sdl-image-1.2.6-r1" |
| 66 |
|
