Description
==========
A vulnerability has been discovered in SABnzbd. Please review the CVE
identifier referenced below for details.

Impact
=====
A design flaw was discovered in SABnzbd that could allow remote code
execution. Manipulating the Parameters setting in the Notification
Script functionality allows code execution with the privileges of the
SABnzbd process. Exploiting the vulnerabilities requires access to the
web interface. Remote exploitation is possible if users exposed their
setup to the internet or other untrusted networks without setting a
username/password. By default SABnzbd is only accessible from
`localhost`, with no authentication required for the web interface.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
All SABnzbd users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-nntp/sabnzbd-4.0.2"
