Newsbeuter: User-assisted execution of arbitrary code


1.  Gentoo Linux Security Advisory

Version Information

Advisory Reference GLSA 200809-12 / newsbeuter
Release Date September 22, 2008
Latest Revision September 22, 2008: 01
Impact normal
Exploitable remote
Package Vulnerable versions Unaffected versions Architecture(s)
net-news/newsbeuter < 1.2 >= 1.2 All supported architectures

Related bugreports: #236506


Insufficient input validation in newsbeuter may allow remote attackers to execute arbitrary shell commands.

2.  Impact Information


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


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().


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.

3.  Resolution Information


There is no known workaround at this time.


All Newsbeuter users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-news/newsbeuter-1.2"
