Gentoo Linux Security Advisory

Title: Okular: Arbitrary code execution (GLSA 201311-20)
Severity: normal
Exploitable: remote
Date: November 28, 2013
Bug(s): #334469
ID: 201311-20

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: kde-base/okular
Vulnerable: < 4.4.5-r2
Unaffected: >= 4.4.5-r2
Architectures: All supported architectures


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