Drew Yao (Apple Product Security) and Clay Wood reported multiple
|
|
buffer underflows in the LZWDecode() and LZWDecodeCompat() functions in
|
|
tif_lzw.c when processing TIFF files.

<impact type="normal">
|
|
<p>
|
|
A remote attacker could entice a user to open a specially crafted TIFF
|
|
file with an application making use of libTIFF, possibly resulting in
|
|
the remote execution of arbitrary code with the privileges of the user
|
|
running the application.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>

<resolution>
|
|
<p>
|
|
All libTIFF users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=media-libs/tiff-3.8.2-r4"</code>
