Synopsis
========

A heap-based buffer overflow in Okular might allow a remote attacker to
execute arbitrary code or cause a Denial of Service condition.

Background
==========

Okular is a universal document viewer based on KPDF for KDE 4.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  kde-base/okular             < 4.4.5-r2               >= 4.4.5-r2

Description
===========

Okular contains a heap-based buffer overflow  in the RLE decompression
functionality in the TranscribePalmImageToJPEG function in
generators/plucker/inplug/image.cpp.

Impact
======

A remote attacker could entice a user to open a specially crafted PBD
file using Okular, possibly resulting in execution of arbitrary code
with the privileges of the process, or a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Okular users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=kde-base/okular-4.4.5-r2"
