Severity: Normal
   Title: Newsbeuter: User-assisted execution of arbitrary code
    Date: September 22, 2008
    Bugs: #236506
      ID: 200809-12

Synopsis

Insufficient input validation 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        < 1.2                           >= 1.2

Description

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

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

There is no known workaround at this time.

Resolution

All Newsbeuter users should upgrade to the latest version:

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