Synopsis
========

Multiple stack-based buffer overflows have been reported in PDFlib.

Background
==========

PDFlib is a library for generating PDF on the fly.

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

    -------------------------------------------------------------------
     Package            /  Vulnerable  /                    Unaffected
    -------------------------------------------------------------------
  1  media-libs/pdflib     < 7.0.2_p8                      >= 7.0.2_p8

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

poplix reported multiple boundary errors in the pdc_fsearch_fopen()
function when processing overly long filenames.

Impact
======

A remote attacker could send specially crafted content to a vulnerable
application using PDFlib, possibly resulting in the remote execution of
arbitrary code with the privileges of the user running the application.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All PDFlib users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-libs/pdflib-7.0.2_p8"
