Gentoo Linux Security Advisory

Title: Xpdf, Poppler: Heap overflow (GLSA 200602-04)
Severity: normal
Exploitable: remote
Date: February 12, 2006
Bug(s): #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: app-text/xpdf
Vulnerable: < 3.01-r7
Unaffected: >= 3.01-r7
Architectures: All supported architectures

Package: app-text/poppler
Vulnerable: < 0.5.0-r4
Unaffected: >= 0.5.0-r4
Architectures: 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:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/xpdf-3.01-r7"
All Poppler users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/poppler-0.5.0-r4"
