Severity: normal
Exploitable: local, remote
Date: 2020-07-27
Bug(s): #712490
ID: 202007-47

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: kde-apps/okular
Vulnerable: < 19.12.3-r1
Unaffected: >= 19.12.3-r1
Architectures: All supported architectures


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