Synopsis
========

pdftohtml includes vulnerable Xpdf code to handle PDF files, making it
vulnerable to execution of arbitrary code upon converting a malicious
PDF file.

Background
==========

pdftohtml is a utility to convert PDF files to HTML or XML formats. It
makes use of Xpdf code to decode PDF files.

Affected packages
=================

     -------------------------------------------------------------------
      Package             /  Vulnerable  /                   Unaffected
     -------------------------------------------------------------------
   1  app-text/pdftohtml      < 0.36-r2                      >= 0.36-r2

Description
===========

Xpdf is vulnerable to integer overflows, as described in GLSA
200412-24.

Impact
======

An attacker could entice a user to convert a specially-crafted PDF
file, potentially resulting in the execution of arbitrary code with the
rights of the user running pdftohtml.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All pdftohtml users should upgrade to the latest version:

     # emerge --sync
     # emerge --ask --oneshot --verbose ">=app-text/pdftohtml-0.36-r2"
