Severity: Normal
Title: Newsbeuter: User-assisted execution of arbitrary code
Date: September 22, 2008
Bugs: #236506
ID: 200809-12
Insufficient input validation in newsbeuter may allow remote attackers
to execute arbitrary shell commands.
Newsbeuter is a RSS/Atom feed reader for the text console.
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-news/newsbeuter < 1.2 >= 1.2
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.
There is no known workaround at this time.
All Newsbeuter users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-news/newsbeuter-1.2"
