Xpdf is a PDF file viewer that runs under the X Window System.
|
|
Poppler is a PDF rendering library based on the Xpdf 3.0 code base.
|
|
GPdf is a PDF file viewer for the GNOME 2 platform, also based on Xpdf.
|
|
libextractor is a library which includes Xpdf code to extract arbitrary
|
|
meta-data from files. pdftohtml is a utility to convert PDF files to
|
|
HTML or XML formats that makes use of Xpdf code to decode PDF files.

<description>
|
|
<p>
|
|
Chris Evans has reported some integer overflows in Xpdf when
|
|
attempting to calculate buffer sizes for memory allocation, leading to
|
|
a heap overflow and a potential infinite loop when handling malformed
|
|
input files.
|
|
</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
By sending a specially crafted PDF file to a victim, an attacker
|
|
could cause an overflow, potentially resulting in the execution of
|
|
arbitrary code with the privileges of the user running the application.

<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

|
<p>
|
|
All Poppler users should upgrade to the latest version:
|
|
</p>

|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-text/poppler-0.4.3-r4"</code>
|
|
<p>
|
|
All GPdf users should upgrade to the latest version:
|
|
</p>
|
|
<code>
