SDL_image is an image file library that loads images as SDL surfaces,
|
|
and supports various formats like BMP, GIF, JPEG, LBM, PCX, PNG, PNM,
|
|
TGA, TIFF, XCF, XPM, and XV.

|
<p>
|
|
The LWZReadByte() function in file IMG_gif.c and the IMG_LoadLBM_RW()
|
|
function in file IMG_lbm.c each contain a boundary error that can be
|
|
triggered to cause a static buffer overflow and a heap-based buffer
|
|
overflow. The first boundary error comes from some old vulnerable GD
|
|
PHP code (CVE-2006-4484).
|
|

|
<impact type="normal">
|
|
<p>
|
|
A remote attacker can make an application using the SDL_image library
|
|
to process a specially crafted GIF file or IFF ILBM file that will
|
|
trigger a buffer overflow, resulting in the execution of arbitrary code
|
|
with the permissions of the application or the application crash.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All SDL_image users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=media-libs/sdl-image-1.2.6-r1"</code>
