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
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  net-news/newsbeuter          < 2.9-r3                  >= 2.9-r3 

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

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

Impact
======

A remote attacker, by enticing a user to open a feed with specially
crafted URLs, could possibly execute arbitrary shell commands with the
privileges of the user running the application.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Newsbeuter users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=net-news/newsbeuter-2.9-r3"
