<p>
PDFlib is a library providing functions to handle PDF files. It
includes a modified TIFF library used to process TIFF images.
</p>
</background>
<description>
<p>
The TIFF library is subject to several known vulnerabilities (see
GLSA 200410-11). Most of these overflows also apply to PDFlib.
</p>
</description>
<impact type="normal">
<p>
A remote attacker could entice a user or web application to
process a carefully crafted PDF file or TIFF image using a
PDFlib-powered program. This can potentially lead to the execution of
arbitrary code with the rights of the program processing the file.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All PDFlib users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=media-libs/pdflib-5.0.4_p1&quot;</code>
</resolution>
