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"
