Insufficient input validation in newsbeuter may allow remote attackers to execute arbitrary shell commands.
|Package||net-news/newsbeuter on all architectures|
|Affected versions||< 1.2|
|Unaffected versions||>= 1.2|
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.
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"
