Synopsis
========

Insufficient input validation in Newsbeuter may allow remote attackers
to execute arbitrary shell commands.

Background
==========

Newsbeuter is a RSS/Atom feed reader for the text console.

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

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

Newsbeuter does not properly escape shell meta-characters in the title
and description of RSS feeds when bookmarking.

Impact

privileges of the user running the application.

Workaround
