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"
