FreeBSD : Okular -- Local binary execution via action links (c3600a64-64ea-11ea-bdff-e0d55e2a8bf9)

high Nessus Plugin ID 134467

Language:

New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

Albert Astals Cid :

Okular can be tricked into executing local binaries via specially crafted PDF files.

This binary execution can require almost no user interaction.

No parameters can be passed to those local binaries.

We have not been able to identify any binary that will cause actual damage, be it in the hardware or software level, when run without parameters.

We remain relatively confident that for this issue to do any actual damage, it has to run a binary specially crafted. That binary must have been deployed to the user system via another method, be it the user downloading it directly as an email attachment, webpage download, etc. or by the system being already compromised.

Solution

Update the affected package.
