GLSA 201311-20: Okular: Arbitrary code execution

Severity:normal
Title:Okular: Arbitrary code execution
Date:11/28/2013
Bugs: #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 Vulnerable Unaffected Architecture(s)
kde-base/okular < 4.4.5-r2 >= 4.4.5-r2 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:

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