Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D

A vulnerability in Newsbeuter may allow remote attackers to execute
arbitrary shell commands.

Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

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

Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

——————————————————————-
Package / Vulnerable / Unaffected
——————————————————————-
1 net-news/newsbeuter <=3D 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
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

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

Impact
=3D=3D=3D=3D=3D=3D

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
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

There is no known workaround at this time.

Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

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

# emerge –unmerge "net-news/newsbeuter"
