PDFlib: Multiple overflows in the included TIFF library — GLSA 200412-02

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

Affected packages

Package	media-libs/pdflib on all architectures
Affected versions	< 5.0.4_p1
Unaffected versions	>= 5.0.4_p1

Background

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

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"
