ID: 200412-02

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"
