Synopsis
=======
Poppler is affected by a memory management issue, which could lead to
the execution of arbitrary code.

Background
=========
Poppler is a cross-platform PDF rendering library originally based on
Xpdf.

Affected packages
================
     -------------------------------------------------------------------
      Package           /  Vulnerable  /                     Unaffected
     -------------------------------------------------------------------
   1  app-text/poppler     < 0.6.3-r1                       >= 0.6.3-r1

Description
==========
Felipe Andres Manzano reported a memory management issue in the Page
class constructor/destructor.

Impact
=====
A remote attacker could entice a user to open a specially crafted PDF
file with a Poppler-based PDF viewer such as Gentoo's Xpdf, Epdfview,
or Evince, 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 poppler users should upgrade to the latest version:

     # emerge --sync
     # emerge --ask --oneshot --verbose ">=app-text/poppler-0.6.3-r1"
