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
-------------------------------------------------------------------

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"
