<p>
Kees Cook from the Ubuntu Security Team reported that the
CairoFont::create() function in the file CairoFontEngine.cc does not
verify the type of an embedded font object inside a PDF file before
dereferencing a function pointer from it.

</description>
<impact type="normal">
<p>
A remote attacker could entice a user to open a specially crafted PDF
file with a Poppler-based PDF viewer such as Gentoo's Xpdf, Epdfview,
or Evince, potentially 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 Poppler users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=app-text/poppler-0.6.3&quot;</code>
</resolution>
