http://security.gentoo.org/

Severity:	normal
Title:	Xpdf, Poppler: Heap overflow
Date:	02/12/2006
Bugs:	#120985
ID:	200602-04

Synopsis

Xpdf and Poppler are vulnerable to a heap overflow that may be exploited to execute arbitrary code.

Background

Xpdf is a PDF file viewer that runs under the X Window System. Poppler is a PDF rendering library based on the Xpdf 3.0 code base.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
app-text/xpdf	< 3.01-r7	>= 3.01-r7	All supported architectures
app-text/poppler	< 0.5.0-r4	>= 0.5.0-r4	All supported architectures

Description

Dirk Mueller has reported a vulnerability in Xpdf. It is caused by a missing boundary check in the splash rasterizer engine when handling PDF splash images with overly large dimensions.

Impact

By sending a specially crafted PDF file to a victim, an attacker could cause an overflow, potentially resulting in the execution of arbitrary code with the privileges of the user running the application.

Workaround

There is no known workaround at this time.

Resolution

All Xpdf users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-text/xpdf-3.01-r7"

All Poppler users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-text/poppler-0.5.0-r4"
