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"
