Gentoo Linux Security Advisory

Title: Newsbeuter: User-assisted execution of arbitrary code (GLSA 201801-18)
Severity: normal
Exploitable: remote
Date: 2018-01-17
Bug(s): #628796
ID: 201801-18

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: net-news/newsbeuter
Vulnerable: < 2.9-r3
Unaffected: >= 2.9-r3
Architectures: All supported architectures


Description

Newsbeuter does not properly escape shell meta-characters in the title
and description of RSS feeds when bookmarking.


Impact

A remote attacker, by enticing a user to open a feed with specially
crafted URLs, could possibly execute 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:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=net-news/newsbeuter-2.9-r3"
