Synopsis
========

A logic error in Okular might allow an attacker to execute arbitrary
code.

Background
==========

Okular is a universal document viewer based on KPDF.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 kde-apps/okular < 19.12.3-r1 >= 19.12.3-r1

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

A logic error was discovered in Okular, which results in trusting
action links within a PDF, possibly allowing execution of a binary.

Impact
======

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

Workaround
==========

Avoid opening PDFs from an untrusted source.

Resolution
==========

All Okular users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=kde-apps/okular-19.12.3-r1"
