<title>SDL_image: Two buffer overflow vulnerabilities</title>
<synopsis>

the library.

<p>
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.

<description>
<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).
</p>
</description>
<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 &quot;&gt;=media-libs/sdl-image-1.2.6-r1&quot;</code>
