libTIFF provides support for reading and manipulating TIFF (Tagged

<p>
|
|
Two vulnerabilities have been reported in libTIFF:
|
|
</p>
|
|
<ul>
|
|
<li>
|
|
wololo reported a buffer underflow in the LZWDecodeCompat() function
|
|
(CVE-2009-2285).
|
|
</li>
|
|
<li>
|
|
Tielei Wang of ICST-ERCIS, Peking University reported two integer
|
|
overflows leading to heap-based buffer overflows in the tiff2rgba and
|
|
rgb2ycbcr tools (CVE-2009-2347).
|
|
</li>
|
|
</ul>
|
|
</description>
|
|
<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 or the tiff2rgba and
|
|
rgb2ycbcr tools, possibly resulting in the 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-r8"</code>
