Synopsis
=======
PDFlib is vulnerable to multiple overflows, which can potentially lead
to the execution of arbitrary code.

Background
=========
PDFlib is a library providing functions to handle PDF files. It
includes a modified TIFF library used to process TIFF images.

Affected packages
================
    -------------------------------------------------------------------
     Package            /  Vulnerable  /                    Unaffected
    -------------------------------------------------------------------
  1  media-libs/pdflib     < 5.0.4_p1                      >= 5.0.4_p1

Description
==========
The TIFF library is subject to several known vulnerabilities (see GLSA
200410-11). Most of these overflows also apply to PDFlib.

Impact
=====
A remote attacker could entice a user or web application to process a
carefully crafted PDF file or TIFF image using a PDFlib-powered
program. This can potentially lead to the execution of arbitrary code
with the rights of the program processing the file.

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-5.0.4_p1"
