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"
