Severity:	normal
Title:	PDFlib: Multiple overflows in the included TIFF library
Date:	12/05/2004
Bugs:	#69043
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	Architecture(s)
media-libs/pdflib	< 5.0.4_p1	>= 5.0.4_p1	All supported architectures

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"
