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

Description
===========
Xpdf is vulnerable to multiple integer overflows, as described in GLSA

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