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
-------------------------------------------------------------------
1 app-text/xpdf < 3.01-r7 >= 3.01-r7
2 app-text/poppler < 0.5.0-r4 >= 0.5.0-r4
-------------------------------------------------------------------
2 affected packages on all of their 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"
