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"

References
