Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D
Insufficient input validation in newsbeuter may allow remote attackers
to execute arbitrary shell commands.
Background

Affected packages

Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
J.H.M. Dassen reported that the open-in-browser command does not
properly escape shell metacharacters in the URL before passing it to
system().
Impact
=3D=3D=3D=3D=3D=3D
A remote attacker could entice a user to open a feed with specially
crafted URLs, possibly resulting in the remote execution of 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
All Newsbeuter users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=3Dnet-news/newsbeuter-1.2"
