Poppler is a cross-platform PDF rendering library originally based on
|
|
Xpdf.

<description>
|
|
<p>
|
|
Poppler and Xpdf are vulnerable to an integer overflow in the
|
|
StreamPredictor::StreamPredictor function, and a stack overflow in the
|
|
StreamPredictor::getNextLine function. The original vulnerability was
|
|
discovered by Maurycy Prodeus. Note: Gentoo's version of Xpdf is
|
|
patched to use the Poppler library, so the update to Poppler will also
|
|
fix Xpdf.

|
<impact type="normal">
|
|
<p>
|
|
By enticing a user to view a specially crafted program with a
|
|
Poppler-based PDF viewer such as Gentoo's Xpdf, Epdfview, or Evince, a
|
|
remote attacker could cause an overflow, 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 of Poppler:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-text/poppler-0.5.4-r2"</code>
