Synopsis
========

A vulnerability 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                 Vulnerable!
    -------------------------------------------------------------------
     NOTE: Certain packages are still vulnerable. Users should migrate
           to another package if one is available or wait for the
           existing packages to be marked stable by their
           architecture maintainers.

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

Newsbeuter does not properly escape shell meta-characters in an RSS
item with a media enclosure in the podcast playback function of
Podbeuter.

Impact
======

A remote attacker, by enticing a user to open a feed with a specially
crafted media enclosure, 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
==========

Gentoo has discontinued support for Newsbeuter and recommends that
users unmerge the package:

  # emerge --unmerge "net-news/newsbeuter"
