Title:	PDFlib: Multiple buffer overflows
Date:	03/10/2008
Bugs:	#203287
ID:	200803-17

Synopsis

Multiple stack-based buffer overflows have been reported in PDFlib.

Background

PDFlib is a library for generating PDF on the fly.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-libs/pdflib	< 7.0.2_p8	>= 7.0.2_p8	All supported architectures

Description

poplix reported multiple boundary errors in the pdc_fsearch_fopen() function when processing overly long filenames.

Impact

A remote attacker could send specially crafted content to a vulnerable application using PDFlib, possibly resulting in the remote execution of arbitrary code with the privileges of the user running the application.

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-7.0.2_p8"
