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"
